Club Shaft and the Bump

Wed, 06/22/2011 - 15:24 -- Don Trahan

A little while ago I did a tip on "The Bump" and how important it is to make good solid contact with the ball at impact. Well, as it happens, that inspired our Director of Club Fitting, Lynn Griffin, to go even a little deeper. He wanted to emphasize the third element I touched on...club length.

In this video Lynn gives an excellent demonstration of "The Bump" and what it actually looks like. Lynn's emphasis is on club length, especially the driver. He shows that if the driver is too long it's physically impossible to "bump" which is key to power and distance in the Surge Swing.

Club length also has to do with your ability to consistently hit the sweet spot with the driver. If the shaft is long, it's harder to control and lack of control means the possibility of more errors. Lynn uses his own "8/10 rule." You have to hit the ball in the sweet spot 8 out of 10 times. If that's not the case, check your club. (Of course my personal rule is 10/10, thank goodness Lynn can take some kidding.)

"The Bump" is power. "The Bump" is distance. Don't swing without it.

Keep it vertical,

The Surge!

All you fellow DJ trackers, given that today's rounds were suspended due to electrical storms before the first flight even finished, his first round tee time is now tomorrow morning at 8:43 Eastern time. That's a Day 1 round, and he'll still have to follow it with his day 2 round. Time to show them your stamina and the power of your ProFuse, DJ. Tear the course up tomorrow and leave it begging for mercy.

Hi Brian, its good when you practice that you work on swings thoughts and other pointers so as to improve your ball striking.   The most frustrating moments about golf for me come from the practice range because I am thinking about the mechanical aspects of the swing as I am trying to continuously improve.   

BUT the most enjoyable aspects of the game is when I'm playing on the course and I feel the swing and swing the feel, i.e. I'm not thinking about the mechanics of the swing, which I think Robert F was alluding to.   You might have a few swing thoughts on the day that you make a few practice swings with, but then you get a feel for the swing you want to make and then swing that feel, having no thoughts about the mechanics whatsoever.   The only mechanics on course that you worry about is #1: proper alignment and #2: a proper smooth rhythm.  Regards, Craig

Sounds like a great experience Boog. I'm happy for you and hope you really enjoy the new clubs.
Can't believe you've been sandbagging me though. "Swings like DJ". Are you kidding me? I certainly wouldn't be able to play a respectable round with anyone even mentioned in the same sentence with a Tour player, especially that one. Ha ha!
Hey maybe hitting something hard IS a Bama thing. Now for the harder part of making it go where we want it to go a little more often.LOL

I believe the arms should be extended at impact also but not extended at the ball. If they are the only way to not have the club head well outside of the ball would be to have it out there at address, as Moe Norman did, or pull up or out with the upper body at impact. (Which I struggle with on a driver swing, but not so much lately). If you get into your address position and then extend your hands toward the ball the club will be well outside of the ball and the longer the club the more outside the club head would be.

I know I'm not telling you anything that you don't know but I wouldn't want a bunch of people to try setting up with the hands under the chin and thinking they can extend them toward the ball at impact and that extra length it would create just magically disappears.

P.S. This whole conversation prompted me to go back and watch the last driver swings I have on video frame by frame and it appears that my hands start down toward the toe line (as I want them to do) but start going in the direction of the ball until at impact my arms are pointing just barely short of the ball causing me to have to raise up slightly to make proper contact (not what I want).
Then I did the same thing with DJ's swing and was very impressed that his arms never extend toward the ball at all, even at impact. This allows him to maintain the proper spine angle through the ball with no pulling up at all.
Tells me what I need to work on even more than I have been. I thought I was getting relatively close but compared to DJ I'm a million miles away.

Ended up not making it out of the house. I'm hoping today I can at least get to the range, though there's no way I could get out to play 18.

Thank you so much for sharing this! And sorry about your hand - I hope it heals well and soon.

I bought a set of Adams A7's (demo days w/Adams at Golfsmith) last year before I started reading the blog, bought Surge's videos, and then learned about real club fitting. I'm planning on getting over to see Russ Ryden over at Fit2Score in the near future. If you saw my swing you'd wonder if it was worth it, but it seems that there are a lot of benefits in getting a proper fitting.

Enjoy your new clubs!

There are currently no certified fitters outside the US (you can check by hovering your mouse over the Golf Instruction tab at the top of the page and clicking on Certified Fitters). However, that does not mean that there aren't perfectly capable fitters in Australia. The best advice is to go to Doc Griffin's site (www.docgriffinfolf.com) and read the information there about what a proper fitting should involve. Be sure that any fitter you work with realizes that you intend to use a vertical swing.

If you scroll down a little on this page: http://dyn.pga.com/improve/tip... you will find a chart of recommended starting lengths for driver and 5 iron based on a person's wrist-to-floor measurement (and a little instructional information to be sure you measured correctly).

Doc, I acknowledge my lack of knowledge in the area of MOI. However, I am curious as to how it relates to swing speed. Boogm stated that with a driver club head speed over 100, his MOI was at 2850. My swing speed is slightly below 80, with a very close MOI of 2823. Is the area of 2800 MOI a target area to arrive at, or are both of our MOI's just coincidence. I know it means moment of inertia, resistance to twisting, ect, but, I am curious for a little more knowledge as to target standards if any exist for the various clubs.
 
One other thing. I hit my 3/4 20* Hybrid fairly well 90% or better of the time, about 175yds. Do you think it would be wise or foolish to have a 2/3 Hybrid approx 15-16* made for the longer second shots.

Thanks,

Robert:  I am pretty sure the new shaft tips will be a bit more flexable, but maybe not enough to change the dynamic lie.  I should be receiving the clubs back tomorrow, or Saturday and will check them after swinging them a bit first.

Steve,
I just wanted to commend you for your humble response to longfellow or whatever he calls himself. Anyway it seems like another troll looking to make us all go wow to his length. I was going to say something to him but we've all been down this road before. Maybe it's the same guy from the not too distance past. We can only hope he gets bored when he realises none of us care about long driving as a priority but in the fairway consistantly.
Anyhow, I thought you handled it well and you are a man I'm proud to have as part of our Surge family.

It changes the relative stiffness in that it changes the swing weight. It may also change other properties about the shaft depending on where you trim it and how much. The simple solution to the first problem is to use lead tape to add weight back to return the club to something approximating the old swing weight (or adjusting to find a swing weight that works better for your wife through trial and error). The best solution is to find a qualified fitter to measure your wife's swing properties and make clubs that actually fit her.

Iam not here to debate you or get into any confrontations with you. Iam sorry about your medical condition and then I will say ---your swing looks dame good for all that going on + I did know  you have been playing for 7yrs.
Steve, you think your a vertical swinger__but your not __ I know why you think your a vertical swinger after watching your video__keep thinking your a vertical swinger because that swing is doing you justice and if your nerves ever come back to you ( your going to beat the ball ) long and straight and from the waist-up your perfect.
Keep up the good work

Craig63 - I have a Cleveland Launcher 9.5* and a stiff shaft. If you would like it, just let me know and It is your just for shipping charges. Lynn has my personal email so you can send me your mailing address through him or just ask him for it if he has yours. That way the whole world doesn't know too much about you.

Bar is a month away. This is the absolute worst thing I have ever done. I have learned a lot about myself in these last few weeks, especially in discovering how I react to extreme pressure. No matter the outcome of this exam, I will come out with a better understanding of who I am, and what my strengths and weaknesses are.

I will get your information and contact you when I am looking for a break.

Doc,

Just watched the video for the 4th time.  As you know I'm one of the "bump challenged" on the site.  Your advice to me sometime back was not to worry about it, just let it happen.  It seemed to work for awhile, but I'm  starting to get more of a slide move than a bump.  I may not be maintaining outward pressure enough with my knees or I may just be overthinking the whole thing again.

RM:  I got an old Bushnell Laser 600-yard "Hunting Rangefinder" on eBay for about $20.  It works great at the range for measuring distance to the concrete posts, island flags, trees, etc.   I use it a lot and it is very accurate.  It takes all the guesswork out of trying to figure club distance.  It is bulky, so I never carry it when playing a round; I just use my Garmin GPS.  Anyway, just another possibility.  Take care, R2

It was a little slower but the same as my old driver and my driver swing was way off yesterday losing everything right which normally I missed left with the old driver. After seeing my swing yesterday on his computer with the driver I know what I need to do to fix it I was way over swinging and had too much side to side head movement not up and down plus I have been fighting some kind of the last couple of days really did not have a lot of energy when I got there yesterday and wore out kind of quickly I hit a lot of balls. That is one of the reason why I waited on getting fitted for driver I knew I would have the opportunity to play with Bill three or four times this year which I did so he would know my swing beforehand and he knew where I was going with it .
The new driver and shaft as bad as my swing was yesterday I was able to keep everything in the fairway which I was very happy with and also the smash factor was way up144 – 149 with the driver head.  I should have it by next weekend I will let you know more after I hit it a few times I will say this I felt like yesterday when hitting that driver head and shaft with a sub par swing  felt like it had a lot more energy are livelier feel to it I just had way too much wasted movement in my swing to say one way or the other whether or not my swing speed went up or down at this point.

Howdy Gents -

Just dropping in for a minute to see how you're all doing.  I've missed reading about all of your golfing (mis)adventures (and other stuff), but I've been incredibly busy and exhausted and have had so much drama lately that I haven't had a chance to do anything other than find a minute to breathe.  Things have suddently gotten busy at work, had a kid in trauma ICU for a few days, another one with a broken car so I had to cart her all over creation, weddings to go to, another friend passed away -- I've packed a years worth of stuff in about 6 weeks.  I've now got tons of Doc videos to catch up on, so I'll be around a little.  

Plus, I gotta give a shout out to Doc for my driver.  It must be working pretty good because the last few times I've played with the boys, after every tee shot, I'd hear "g**dammit Janet!!"  haha.  Now I'm thinking about irons ...

Steve:  That is SOME swing speed you have!  Way to go!!  I started at a 6 and now am comfortable at a 5, but can get it to click on 4 and 3 with the right bump.  When practicing, I find my "comfort level" for that day and then go to the next lower number for a few swings.  Seems like the SwingRite actually helps increase your swing speed if you use it a while each day.  Yup, it is an AWESOME tool that really works!  R2

doc, ( top to bottom response )
1- You never lower your hands to hit a longshafted driver, that promotes power loss and pulling the club over the top and hitting a duck hook.
2- Long shafted drivers have been around since at least 1985 or 86.
3- I know WHO started the " Long Drivers Of America " and where the idea was concieved and why ? and all we had was a 6 pack of beer, sunflower seeds and over looking the ocean in Florida 15 stories on a veranda
4- my friend let Art Salinger buy in to the LDA, went good for a few yrs, alittle hell broke looseand ended up selling his stock in the LDA to Art.
5- Long shafted drivers were used in the LDA at any lenght but now it's like you said.
6- Don't want to take a physics class with you and I won't refer to a book of numbers, letters and coefficients that can't hit a ball and explain on what it just did or didn't do.
7- The book you took all that info. is good for building not swing a object with the human body

Q: What would all your calculation say if I told you I hit a ball over 400yrds with a slight elevation with a LADIES shaft at 53" long in Arizona ?
I feel like I just gave a short class

Who in the heck are you talking to anyway? You replied to Ron and all he did is ask about fitters.
If you are talking to Doc he knows full well what you would need to do to swing a long club, and it AIN'T vertical.
Different power source and different "advantages".
The advantages for more rotational are:
1. It allows you to successfully swing a longer club (if you have the talent to do it).
2. It allows you to watch almost any instructor that you might see on TV and get something out of what they are saying.
3. It is really good for golf ball manufactures because most of the "golfing public" don't have the timing to square up the club on a rotational path, multiplied more with the drivers that are too long for them to control.
4. It is great for doctors and manufactures of body replacement parts.

The advantages for vertical are:
1. It is naturally how our bodies were designed to swing a club and creates very little stress on the body.
2. The club face is square through the impact zone for longer allowing a much better chance of hitting the ball where you want it to go.
3. For the person capable of hitting long shots distance will be a "wash" or at least close to it. They can swing their arms vertically down on the toe line with more power and faster than they can swing their arms from behind them. Since more rotational allows for the use of longer clubs the rotational swing gains that back with a longer swing radius. (Admittedly oversimplified, but tired of typing). Some people may hit the ball longer with a vertical swing and some may hit it farther with a rotational swing but assuming they are performing each correctly the difference should be very small. The truly gifted "world class" athletes that can really control the much longer clubs will probably lose distance with a vertical swing and a shorter club but they will in all probability hit the ball straighter.

So the question we ask is would we rather hit the ball straighter with what will probably be a "wash" on distance, and stay away from the doctor?
Or would we rather have a good chance of paying for our golf with injuries that can either come quickly or over a period of time on the off chance that we just might pick up a yard or two with a longer club and a rotational swing?

Hey Robert,
Have you tried the ProFuse?
I have been drinking an ounce of it in my water at work for a while now and I believe it has made a difference.
It's very hard to tell the difference between the "dead dog tired" I was after and during work before with the "dog tired" that I am now but I'm pretty sure I feel the difference.

Sorry for the confusion guys!!...Guess I should explain my original problem was prob. hanging back too much on my right side...way too much bump...lil left arm chicken wing...no real extension thru the ball (not maximizing my power)....hope that helps. What really helped me was seeing Surge go up and then showing the arms extended towards the ball...I started to realize I wasnt doing this. For me...this thought of extending the arms thru the hitting area shortened my bump naturally....and I dont think about the bump. This is my only swing thought now and haven't hit the ball this good in awhile!....I think some people get bump happy and end up forgetting about where the arms should be. I feel if you practice swinging nice and slow and try to get to the ball extended and thru...you'll notice the body hopefully will bump naturally with less movement..

I bought one and was amazed at how it corrected items in my swing that I thought I was correctly doing.  It definitely made me sense/feel the position of the club, hands, and arms throughout the entire swing because you can only swing it accurately.  One suggestion, keep using it as you tend to go back to your old ways if you suddenly believe you have it all together.  It also does not take too much time to practice.  Hope it works out for you as it has for me.

Hey T.
At least you don't have to make a decision on game day which club gets to sit on the bench for the day. Ha ha!

For me the dilemma on game day is between the lob wedge and the 5 wood. Lately the lob wedge gets in because as long as I'm hitting my irons well I can step it up a little with the 3 iron and fill the gap to the 3 wood anyway.
At Desoto though the 5 wood gets in because there are some shots that I usually have that require a very high slice that carries about 200 yards (at least it does if you want to make birdie) and I can't do that as well with a 3 iron.
Of course if I hit the ball down the middle of the fairway from the tee I wouldn't need that shot but I usually get at least one or two a round on that course that I need it on.

We really need to find a way for you to start playing in the early am. I know you have certain circumstances but I will be playing my 9 before 8am at 5:55am especially during the summer months on work days on Saturdays, Sundays, Mondays and Tuesdays. Normally at least 2 of those 4 mornings(flexible on which). Too I wouldn't mind picking any of the other 3 days(Wed-Fri) to play some morning too if that helps accomodate your 'sitch'. Though I'll play in the afternoon once in a while, those morning rounds are great because they beat the worst heat.

Are you serious?  The only time I'm in the SBG is when I'm demonstrating how you'd have to swing if you were using a club too long which was the whole point of the video that you can't swing a long club vertical.  Did you even watch the video?

And I don't really mean to sound egotisical but don't you think it's rather pious to try and "correct" a certified swing surgeon instructor and a master teaching professional as well?  Do you have some kind of axe to grind with me?

Doc, thanks for the refresher on the bump.  I've been inconsistent in my sweet spot hits.  I'm pretty sure I've been making too much of an initial hip move, both laterally and rotationally.  I'm going to think Nudge, Bump for me is what I did under the basket to move someone out of the way and what the wife does with her well shaped hip when I snore.
