Releasing the golf club, roll release vs body release (pictures/videos included)...

[glk]

I don't see any crossing over. To cross over one would need to have the trail shoulder go internal and further rotate the arm so that by p8 the trail forearm would be on top of the lead forearm as viewed from face on and the trail elbow would be facing away and not pointing at the ground.

Pretty clear that in all of these releases that is not the case and if viewed from the face on we'd see the back of their trail hands versus the side. To roll over the trail shoulder has to go internal otherwise in the downswing the forearms (from elbow to wrist) are both supinating and at just prior to impact the trail forearm pronates while the lead continues supinating - the forearms only are involved in the supination/pronation - had they been rolling over one would see their trail elbows pointing away from them versus pointing down to the ground. Rolling over is a poor term, imo, since in good releases the forearms never roll over or cross - not even past p8 - and even in "poor" releases one doesn't really roll over - it's just poor sequencing that results in a late, rapid squaring.

Early in Tyler's video he demonstrates the difference in performing the throw move with body rotation versus throwing the club at the target with a body stall - going to have later and faster supination in the latter with resulting inconsistencies.

I don't think that is the case, in all these cases they are at full extension well after the ball, hips pointing towards the target, which is largely the intent of the planemate (shallowing properly while keeping the arms in sync with the pivot).

Yes, you are right. I can see it now. 2D is really not helpful.
