Is there benefit (greater than any possible biomechanical disadvantage) to having flat lie angles on irons and woods...thinking ABS again...not anti-ABS....but would like an expert scientist view on some of their claims.

1. Advantage(s), if any, of getting to the elbow plane early in the downswing vs. staying on the shoulder plane.
2. Most advantageous weight/pressure distribution between feet throughout the swing--particularly in the downswing to impact.
3. Optimum amount of hands following the hips/shoulders in the downswing sequence. Or what is the optimum amount of hip/shoulder rotation on the downswing compared to the position of the hands in the downswing? (Relate to #2 as well).
(could you pm me or post the consensus, since I am unable to make it?, thanks

Where does low point occur? Is it below the shoulder socket? Below the center of the sternum as the golf fix indicated tonight? And can you control low point better with a centered pivot?

Pet topics too numerous, so an open-ended question, I’m afraid.
Is golf a science or an art?
Would be interested to hear the opinions of the scientists and the golfers.
How do the scientists think their findings are best used by golfers, and how do golfers think the scientists output can be best applied to change the way they hit the golf ball?
Is objectivity achievable? Will the mathematician ever be able to discuss with the physicist, hand over to the biomechanist, tag in the psychologist and finally pass over to the golfer to develop ‘laws’ the golf swing? How could this be tested without recruiting hundreds of identical twins?

Is there a pattern which might balance out optimization with ease of performance on the body? In other words maybe there is a pattern which would be best for allowing people to play good golf for longer as they get older.
I am wondering about this as my father in law is thinking of taking up golf at age 63. He is reasonably fit but.........

No opinion questions....
If they don't "kick us out" of the meeting room after 5pm, we may stay and argue thing like those I listed above which are purely opinion, mental, or beyond the scope of this symposium.
Lots of the other questions are "on the list."

I understand that time is short, and hell, you're chairing the discussion and I won't be there at all, but doesn't this limit the scope of what's achievable?
You should get some good answers on how a swing generates and transmits force to the clubhead - but I don't understand how you can get any clear-cut answers about how to achieve good impact alignments.
For instance - what makes an open face a fault? Most people can't square it at impact consistently. But some people can, and some people can square it occasionally. So how can you draw any conclusions about the open face being a fault unless you've got some basis for classifying flipping it closed as a compensation rather than good technique.
Similarly, loads of people justify their swing theories by claiming that they reduce the amount of timing or talent required to hit the ball consistently. This is just my opinion, but unless you try to break down some criteria as to what timing can and can't do in the swing then, at least from an accuracy and consistency point of view, you're left with a bit of a free-for-all in which any old loopy swing is fine as a matter of technique and the only real problem to solve is one of hand-eye co-ordination and timing.
I know you're not tied to any one method, so maybe this doesn't directly impact so much on what you teach. But if you want to critique other methods and their claims, then surely you've got to deal with this?
Within the realm of normal clubhead speeds, does changing the clubhead speed, all else the same, change the launch angles?
For example, when going from 90 mph driver speed to 100 mph speed, all else equal, will the launch angles change by any appreciable degree?
I'd like to hear Dr. Wood's specific answer to, "Does the coefficent of friction between the ball and clubface change significantly due to clubhead speed?"

What factors maximise backspin on a less-than-full wedge shot?
Sound of impact
Any evidence to support the claim you sometimes read about certain great ballstrikers like Hogan, Moe Norman, etc...
"Even the sound at impact is different !"
Or is it merely the same sound for anyone's similarly well-struck shot, and maybe they just repeat it more often than others.
And can this be re-produced on a PingMan or Iron Byron ?

Muscle contribution/power generators...
Realities/stats of alignment and aim...? Or maybe this "has been done."
Hopefully I can come up with more. Need to go to bed.

Weird phenomenon
Why do almost all golfers hit the next ball fat after practicing David Lee’s (Gravity Golf) “No Reference” drills?
The “No Reference” drill has the golfer hit shots from a non-standard address position. It requires that the golfer walk into a golf ball with the club shaft held vertically in front of his chest, thereby bypassing the arms/club unit as a way to measure the distance he stands to the ball. After setting the feet, the golfer pushes the hands straight up, pivots back and hits the shot. Lee calls it proprioception, the ability to locate a position with the hands because you’ve been there before. He states that proprioception can work against a golfer’s ability to return the club impact in the most beneficial and “physics compliant" way.
Has anyone else here experienced this? If so do you have any theory about why?

How about a question on Snapping The Chain.
1) Is it valid
2) is it perhaps the only real way (or the best way) of getting close to 100% of max clubhead speed?
3) How small of a chain can be made to achieve good results? - something like left hip, left arm, left wrist?
4) Can braking of the parts be consciously controlled, or just the stoppage of the intial segment?
