Intersting stuff. But for the purposes of discussion can someone please define Snap Release. Let's all get on the same page here.
And at the risk of preaching to the choir I'd like to point out the benefits of earlier than snap as utilized by Mr Hogan. release point being a Machine adjustment . Jack couldn't hit a sky high cut 2 iron without Random Sweep!!! Luke Donalds sand shots wouldn't work with a snap release !!
For practical purposes, the shaft should be horizontal or above when the butt of the left hand reaches the right thigh on the DS. Some snap releases are snappier than others.
