915D2 12 or 915F 13.5 ??

Wow, thanks for all the replies, I guess I am not alone. For now I will experiment with the 915D2 12, cut it to 44 inch and change the weight on the bottom so it will be back to D2 and maybe ad a little loft. If that does not help I will try the 13.5 915F. Thanks again for all your help.
