910/913Fd 13.5 at A4 vs 15 at A1:
In theory both of these clubs are set at standard lie with a loft of 15 degrees, ON PAPER. Is there any difference in reality if i were to hit them, i.e. the head is a little closed/open on the 13.5 vs the 15 at A1.
I have a 910Fd 15, set to D2 and love it. Sometimes i wouldn't mind a flatter ball flight. Was thinking i could get a better range with the 13.5.
Thanks in advance for any thoughts.
