Mike -

Would the lead deflection cause the leading edge to be in front of the handle all of the time? Or does it depend on the loft of the face?

I don't know if I can answer your question directly, but he did say that one of the things they measure is kick velocity of the shaft going into lead. He also mentioned that after shafts kick into their max lead, the shaft then "backs up" and takes the velocity reading down. It sounded like that was a big part of Fujikura's fitting process - to find a shaft that does the least backing up possible (or at least find a shaft that comes close to delivering the best kick velocity bonus to the player)......

Your question is a good one and should be addressed when we go out there.

Art, how does this jibe with Steven Nesbit's observations?

Mike,

Looking at Dr. Steves early research paper on Power, Work and Energy, he quantified the amount of work being done for all the body elements he modeled. I obtained this paper 'when the ink was still wet', and corresponded with him regarding the incredible gift he gave us all. So, this 'energy' approach to the golf swing is the cornerstone of my approach to understanding the complexities of this body/club/ball/earth integrated problem.

Steve's calculations for the 4 golfers characteristics in Table 2, with 100% efficiency, did/contain sufficient work/energy with these upper body elements ALONE (ie shoulder complexes, elbows, and wrists) to produce the noted club head velocities.

While the overall 'efficiency of the 4 golfers , as I recall, ranged from 20 to 27 %, I strongly believe the efficiency of these upper body elements are VERY efficient, and provide a large part of the energy required to develop the indicated club head velocities.

So, the reality of this situation again becomes golfer and swing specific, but IMO a lot of attention should go into this area as much of the energy AND much of the club head's trajectory (approach/path), and attitude ( club face angles), are influenced by these body elements.

Thanks Mike. Interesting and fascinating issue.

Thanks, Art - I always appreciate your posts.

Thank you Art

Like Mike said, I too enjoy reading your posts.

I tried the hips adjustment at address today and had some positive results.

I'll report back when I have some reliable numbers to go along with the swings.
