Bagger, I noticed that while I was practicing bunker shots, if I concentrated on PP#2, I would execute horizontal hinging better, and also finish swivel with a flat wrist. Would this be something for a swinger to translate to regular shots?
The first question that comes to mind is, how do you know you were horizontal hinging, and why were you doing it in a bunker?
It is certainly an option, I'm just curious about the evidence you were getting in the bunker.
My second reaction to the question is if you are getting better horizontal hinging and finish swivel while concentrating on pp #2, then by all means take it out of the bunker!
I'm still contemplating the role of the continued drag of pp#2 against the clubshaft through impact, into the follow through and finish. It certainly would seem to be one of the primary feedback mechanisms for keeping the hands ahead of the clubhead.
