I currently play 710 AP2 irons with Project X 5.0 shafts. I hit my 7 iron 145-150 and am currently an 8 but usually play to a 6. I am 64 years old and 5' 5", 150 lbs. I am considering AP2's with either the new XP95, R300 shafts or the stock graphite shaft, Kuro Kage in either a stiff or regular flex. When I compare shafts the Project X shafts seem to be 15% heavier! Suggestions?
