The known factors:
Volvik Crystal L51+: Dist 4.0, Spin 4.0, Meter 3.0
Beth Black 1st hole. Big bunker right side of pin.
14yd, 4ft Up, 30/40 Lie.
I prefer flop shots around the greens within 30 yds from fairway, rough and bunkers.
Flop 60wdg 23yds full center ball. at 100% carry 7yd, roll 10yd. Well past the hole. at 97% goes 8ft past hole. and at 96% it doesn't make the green just stops on the edge in the rough.
Maybe some of you experts can give me some advice. A difference of 1% to get on the green is kinda crazy.
