I have project x 5.5 in my AP2 irons and I'm not getting a lot of distance out of my irons, 7 iron goes about 145. I recently hit a launch monitor and my ball speed average was 115. I have two questions: 1. With a 115 ball speed is my swing speed is 80? 2. I was thinking of getting project x flighted. Should I go with 5.0 instead of 5.5?
