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!

Robert,
As usual he is only promoting his own agenda. Some things never change no matter which new name you use.

How was you club head speed compared to a shorter driver?  Ball speed?

Doc,

Just a note to let you know that the clubs you made for me arrived this afternoon. Look and feel great. I will be trying them out in the AM before I go to work.
Will let you know the outcome.

I'm glad you brought the whole conversation up. It caused me to do some studying and came away with two conclusions.
1. DJ is very, very impressive. (Even more than I thought and that's a bunch).
2. I sure ain't him. Ha ha!

Maybe I can take my range time out at Paiute and warm up with you before your round. If I can be sufficiently convincing, I may even manage to play the first 9 with you, but that's a big if.

Yes it is a pretty easy way for anyone to check the lie angle during the swing.  I recently sent my fitter back 4 clubs that he made for me so he could install a more flexable shaft.  The first shafts were a bit stiff for my swing.  It will be interesting to see if the dynamic lie angle of these clubs changes with the different shafts.  I would think I'd have a bit more toe down.  When the fitter checked the orginal clubs the black marker line was slightly tilted inward, but not enough in his opinion to change the lie angle of the club.

MOI only refers to resistance to twist when talking about the club head itself.  MOI of the club is referring to the effort that it takes for the individual to swing the club around the axis of rotation, themselves, and bring the club back to square.  The MOI should be the what the individual "feels" and controlls.  My MOI is 2800.  DJs is 2900.  I have some other stronger players that have MOIs at 3000.  It is all about feel and control.  Once you find the "magic" number then you can build any like club to that spec and it will play the same.

83 T? Another nice round. I'm liking the swingrite alot so far. As for those figures,with my speed I'm mid eigties-mph with irons and mid to ocassionally high 90's with the driver. So 5 and potentially 4 sounds about right for me. Got comfortably down to 5 last night after only 3 days of practice. It sure makes alot of things easier like vertical and the T finish.

As stated below,  I do not like 460cc heads and see absolutely no good reason for them and can list more reasons to avoid them like the plague.  How tall you are has little to do with the length of club.  It's how far your hands are off the floor which has to do with arm length.  But, to answer your question, if  you want a driver at that length to have the same feel as at a longer length or as a 3 wood (normal length is 43.5"), the head would need to be weighted more like a 5 wood in the 220 gram range for starters.

Hey Craig,

Great points. What I was talking about, though, is Doc Griffin's recommendation not to think about the bump at all, in large part because when we think about it, we end up making it something a lot bigger than it is. He demonstrates very well in this video just how subtle a move the bump really should be. I really appreciate this as I'm sure I have also been making too much of the bump and this should really help.

Very good point,Doc.  I had narrowed my stance to avoid swaying and may have overdone it.  If it ever stops raining I'm looking at that and maintaining outward knee pressure.  Thanks.

I was wrong actually 35 1/2.  I hit 44 " all over the face  43 3/4 all over the face 43 1/2 all over the face. At 44 1/2 I was dead center every time a little high on the face but was able to swing unrestricted with that length it felt really good. I am in between vertical and rotational with the drivers right now and it is costing me big time.What I seen on his computer was my head was moving 5-6 " back in the back swing and back to the ball to slightly past at impact and I was coming in a little steep all so. All in all at 44 1/2 the swing speed was slightly faster and a little longer distance with the 44 1/2 inch driver even though my swing yesterday was horrible I still kept it in the fairway. I am going to have to work on tee height with this new driver also I kept wanting to tee it to high were i normally tee my ping.

I normally carried my driver around 250 plus 10 - 20+ yards of roll depending on the conditions.
I really do not think I am going to have a issue with distance at 44 1/2 but I will report back on it after I get the driver next week and get a couple of practice session with it but he will probably bring it next weekend to our tournament and it will get tested under fire right off the bat LOL.

I am playing two tournaments this weekend at Grand Vic it is a true Irish links course and the fairways normally play fast I am thinking about not even taking a driver this weekend.

The other thing that I will be trying this weekend I went to the eye doctor this evening  its been a couple of years my depth perception is not very good and when I shoot flags with my range finder and get the distance and then look at the flag it looks longer than what I measured . I have glasses with no line bifocals and distance correction I did not have to change the prescription but he did give he did give a prescription to get sunglasses with the distance correction and not the bifocals at least I will be able to see the pins better for what that is worth.

The option is there to go shorter in the future if need be as I get more into this swing but for now 44 1/2 will keep me in the fairway.

Really, shame on you. You really don't get it.  It's an extremely short club and you're looking at me at more of an angle from the back rather than from the side.  So, if you look at the very first explanation of the bump from the view of my side, you'll see the shaft is about 4" from my right ear which is exactly where it's supposed to be.  While I'm talking and demonstrating the hips I do not try to keep the club up there as I have a problem in my left shoulder that got me started on the Surge swing some 20 years ago.  I have some things that I have to work on in my swing, i.e. getting too long in the back swing, but one thing I don't have to work on or worry about is getting laid off or flat.  So, yep, I'm egotistical but I'm also correct.

I believe all the calculations would say, Who gives a shit? This site and the SSGS is here to promote a vertical swing for longevity of play, Not who can hit the ball the furthest from a tee. We promote a body friendly swing, that does not destroy the back, legs, shoulders, and hips, after 15yrs, like the rotational swing has done to Mr Woods and others of his kind. There is more to the game than long drives. We really don't care about your ability to hit a ball a long way.  I beat guys who drive 50 to 75yds past me every day. They can pound a ball, for sure, but they can't play golf worth crap. Just because you can drive a ball 400yds, doesn't mean you can play golf. If you could, you would be doing it, instead of just bragging about your success with the one trick pony. Get you head off of the driver and onto the entire game and realm of play.

You have no idea what this swing system is all about, yet you want to argue the issue. Why not try to educate yourself a little on the actual Swing System first. The Foundations Manual, available through this site for a mere $20.00 will fully explain the system to you. At least then you will have some idea what we are talking about. For now you just sound like a big bag of wind, trying to blow your own horn, over shit that none of us give a damn about.

Thanks Doc.......

Since there are no SSGS instructors in Chi-Town I have to rely on the Blog and fellow Surgites for advise.

My bump has been more of a sway, nothing like the slight "nudge" you demonstrated. this I will work on.

Received my Swingrite as well. Started at nine, changed to eight with success. I assume goal is to have "clicks" on every swing, regardless of number?

Please comment......

Welcom back Janet. ICU does not sound like a fun place to be as a parent. Let me know if you need anything. I recenlty ordered a Swing Rite from Doc, so he has all of my contact information.

If you ever need someone to hit the range with, or want to sneak in a quick round out at Pine Glen, let me know. I am always looking for excuses to run away from the bar studying. If you ever want to know what the definition of insanity is, just walk into a law library and look for people studying for the bar exam.

1- I  just saw your swing on your video and u shouldn't be commenting on anyones swing on this blog and your lower body is all over the place.
2- You don't want people to comment on your swing then why do u do it and sound like a know it all when u have only 5yrs with the game. 
3- You don't swing VERTICAL like u claim to on this blog.
4- You are most diffently out of your LEAGUE when talking about the golfswing or anything else in golf.
5- What is this stay away from doc stuff ? who are u to be telling anyone what to do. All I did was comment on the swing plane of a longer driver vs a vertical swing plane and then I get you.
6- You don't know what a Vertical swing looks like, it's funny to look at because it's over the top and totally disconnected from the swing plane and that's all I'am going to say.

Doc, what an excellant explanation of the 'bump' - and how timely !

I posted earlier that I had been having much difficulty with the execution today, and your video has given me a much greater understanding of what it is. I've clearly been moving far too much, and I will try to remember all your pointers next time out - although Robert F tells me I've got to forget about it LOL.

Thanks again, Doc.

Cheers

Lynn,
What makes you think that you don't "bump"?
Is it in videos or are you just "thinking" that you don't do it?
And can you skip a rock without a bump?
I can't.
I think it would be very, very hard to get a SwingRite to click very nicely on a relatively low number without both a bump and letting the hands fall down the slot with the shaft trailing.

Agreed.  And, most people can also not swing a longer driver with accuracy or at the club head speed that they can swing a shorter driver.  I have a long drive team and one of my guys plays a 44.5" driver with 9.5* of loft and puts 6 of 6 balls in the grid and carries the ball 350yds.  Why 44.5"?  That was where his club head speed was the greatest and his contact was in the center of the face.

Take long drive shafts at 47" to 48" (when measured on the top to tip, 50") and the club can not be swung vertically as is the swing that is being taught on this site.  It has to be swung flatter and more rotationally.

Just watched the video.  Funny, that's exactly what I'm talking about.  For a long time, I was overthinking the bump until it occurred to me that maybe it's like what happens when you swing baseball bat, the difference being that the ball is coming at you so fast that you don't have time to think about it.  That's the problem with golf tips -- you (or I guess I should say, *I*) try to incorporate every single tip into your swing, when there are some things you do naturally that should just be left alone, and you end up thinking too much about every little aspect of your swing and then it gets REALLY screwed up.

I just re-read that last line and I don't think I explained what I mean very well, but I'm sure somebody out there knows what I'm talking about!

Doc,
This was one of the best videos on the site. Very informative, about the length of the clubs as it compares to wrist to floor measurement. Solid contact is what we all strive for!

I've been reading your blog for a long time and have not responded to anything as of yet and this is a subject matter thats down my alley. I'am a X pro. longdrive competitor from 1986-2003 and very proficient at hitting a golfball on the screws. In short, I know the swing path of the longer driver and a weapon it can be on the golf course.
Longer is ( NOTHING ) if it is not backed up by accuracy.

HI Steve.
That is some awsome swing speed you have!
When I was considering getting a SwingRite last November I exchanged a number of emails with Kate Whitney, the President of the company. In one of these (and this was because I don't have access to a speed monitor) she was able to advise me of the APPROXIMATE swing speeds for the various settings. Kate did stress that these figures could only be taken as a guide.

For what it is worth, #2 would approximate to 116mph. If you have been tested, is this in the right ballpark? If it is, then I will be happy to share Kate's other figures with the site, but if it's not then it would be better for me not to do so.

By the way, the best I can achieve so far is between #4 and #5 but getting lower as I practice more. I doubt this aging body will ever get near to #2!!!!!!!

Cheers

   I read your post regarding your LEFT leg/ankle.  As one with a similar, though not so severe, weakened left ankle, I feel your pain, Buddy!  And like you, I can not get completely to my left side in the FUS.
   In my case, it results in a considerable loss of clubeh ead speed, but I am able to hit remarkably Straight shots, usually very near to the target line. But the misses are awesome at times. LOL

   Keep hitting them STRAIGHT and LONG,

I don't know Robert. When I "missed the click" on the first try on 2 it made me think that I need to step it up a little. LOL
At least it gives me something to shoot for.

P.S. A nice smooth "Ernie Els" tempo swing clicking that thing on 1 every time would be nice.;-) So I have a ways to go.

You'd be very welcome Robert. I've had a two week delay on my new sticks. We made some changes.They may arrive today. Anyway this may be my last round with my old clubs. I will have my swingrite with me. So if you bring yours we can compare grips. I plan on being out there on the range (for snow mountain- they have two seperate ranges) at about 1:00pm.

I would think that by far the majority of people on this site joined because they wanted a swing that would alleviate the PAIN which comes from the swing you appear to be trying to promote.
I do not think we want to be trying to achieve the longest drive in the world.
We want to be able to hit the ball in the fairway, and be able to do so for as long as we are able to walk.
I, for one, am perfectly happy with what is being offered/taught on this site.
Cheers.

Thanks, Bob, the hand should be fine in a couple of days.I'm already flexing it some to see how that works out. I'm meeting Mike tomorrow over at Doc's place or the range there. I don't know that I'll be able to swing but it will great to meet another Surgite and share swing thoughts and the like.
 Speaking of which, I keep forgetting that I'm in the Doc zone and am a hour ahead of myself,so it actually being 1:35 or so, I better get some shut-eye. After I get back from visiting with Mike, I've promised Josh a trip to Edisto Island State Park. 136 mile day trip,all I can say is I better be able to pick up a diet Dr. Pepper somewhere down there. :)

Too much bump or SWAY can cause you to get out in front of the ball which could very well cause the club face to be open.  It can also cause fat shots as in hitting behind the ball, casting, coming over the top, just to name a few other symptoms.

Twilight Zone tonight Doc. When I film my swing I have to put the camera on the toe line with a good view to tell exactly where I am with the swing.
I guess Fred can tell all of that with a talking video from the thighs up and no perspective of anything, and none necessary for the message.

I keep waiting for someone named Rod Sterling to comment tonight.
"You have just entered........The Twilight Zone".
Ha ha!
