I have a set of AP1's and a set of AP2's. The AP1's have the project X 6.0 shaft and the AP2's have the Project X 5.5 shaft.
I have a set of Project X 4.0 tapered tip 355 iron shafts 4-PW.
I was wondering which set to put the 4.0 shafts in? I'm 67 years old and my swing speed had deterriated some and was hoping to swing easier, with the lighter shaft, and still get some distance with the club. Will I benifet more by putting the 4.0 shaft into the AP1's or the AP2's?
