I currently play 716 ap2s with dg amy shafts. before that i played 712 ap2s with project x 5.5. I am currently looking at switching to some ap3 shafts. looking at the fitting guide for shafts i am thinking project x lz or amy black. The fitting guide shows project x lz 6.0. was wondering how comparable the 5.5 would be to amy black.
