i have a diff wedge ...
but for what u describe its a FLOP for me..
assuming it was level around hole.. .. i take off two yards for roll... but add 8 yards for 40/50
thus 16 yards power is what i will need.. my64 max power is 15 yards... so i dont quite use full bottom...
i use the stop erly on the meter style.. and usally scare the hole,,, make a few..or most always leve a EZ tap in..
hope that helps... even for longer flops with my 60.. like yers... i add 8 yards outa 40/50... just have to pay atten if where it lands is up or dwn hill.. and adjust ..
peace
