Hi, I am new here and am trying to get some information on shaft options as I am getting ready to order a new set. I am currently playing the original Callaway X forged in a PX flighted 5.0. My swing speed on an 7 iron is 88 mph and I hit the ball pretty high as I like to get down into the ball rather than sweep it off the turf. I am getting ready to purchase a set of Titleist AP2 710's. I can either get the px non flighted 5.5 or the now standard DG s300. I would lean towards the PX non flighted but just want to make sure. I dont think the jump from 5.0 to 5.5 is going to make that much of a difference as I probably should have been playing that stiffness all along. Any insight would help.
