Hey JGus...
I just found your thread and had to comment as I've been fighting snap hook hell for a few years now and all my observations are similar to yours... whatever grip I try, I can feel the hands fighting each other to the point that the clubface is closed 45 degrees! and that's just hovering the club at impact. I've tried it all. flat swing plane, high hands, extreme grips, etc...
It has made my game hell as I fidget over every swing now expecting the worst.. playing in fear.
I wanted to know how you're doing it since you fixed it and if you have any feels or moves to recommend to help me/others who have the same issue.
Thanks in advance,
Stephane
