I have been reading an old book by Ed Tischler and noticed an interesting statement he made about golf instruction when golfers moved from hickory shafts to steel. This is what he said:
" The teachers of the day needed to find some way of helping average golfers combat the rolling habits they had developed with hickory shafted golf clubs. The popular answer was to pull with the left hand from the top of the backstroke. By half way down, the clubface would then be positioned in an open position much like it was with hickory shafted clubs.Then the golfer could roll while releasing, just like he did with hickory clubs. This compensation worked well for those golfers that had existing hickory habits. However, it messed up generations of golfers who had never swung a hickory shafted club. By pulling with the left hand, they simply flailed the clubface open, the result being slicing golf shots. So , even though the theory was designed to help golfers with hickory habits, it is still being taught today".
He mentions 'rolling ' as meaning the rolling of the hands to counter the 'torquing open' of the old hickory shafted clubheads to deliver the clubface square at impact.
Does he have a valid point?

He mentions 'rolling ' as meaning the rolling of the hands to counter the 'torquing open' of the old hickory shafted clubheads to deliver the clubface square at impact. Does he have a valid point? No! Even with steel-shafted shafts a golfer (who uses the intact LAFW swing technique) has to roll his GFLW counterclockwise (via a left forearm supination motion) in the late downswing in order to square the clubface by impact - because he pronated his left forearm in the backswing so that he could get his intact LAFW/GFLW parallel to the inclined plane by P3. With hickory-shafted clubs one would have to roll more because the shafts were so flexible that they twisted more open during the downswing action and that resulted in a greater problem of consistently timing the release of PA#3. However, there is no way to avoid using a PA#3 release action with steel-shafted clubs if one does not adopt a very strong left hand grip. Jeff.

Many thanks Dr Mann
On a separate note, I have been reading some of your comments in relation to Tony Luczac's You-Tube videos. Did he ever take up your offer of $1000?
"Tony - If you can show me biomechanical and EMG research that definitively proves that the right sided muscles are responsible for providing most of the swing power in professional golfers (like Dustin Johnson and Rory McIlroy and Adam Scott and Justin Thomas) then I will donate $1,000 to your website"
I think your last communication to him was
"You obviously know very little (if anything) about my opinions regarding golf swing biomechanics/mechanics if you think that I am a TGM-literalist who solely relies on Homer Kelley's TGM book. I have gone well beyond Homer Kelley's TGM principles and I have even shown how Homer Kelley got many of his facts wrong. I will again offer your website a donation of $1,000 if you can definitely demonstrate that the release of PA#4 (release of the left arm) is not the main source of swing power (clubhead speed at impact) in most PGA tour golfers, and if you can prove that the right arm supplies most of the swing power - because those 3 research papers definitely do not provide the necessary proof."
Regards DG
