I was recently fitted for a 915D2 - 9.5 degree loft with the Diamana S+ Blue Stiff shaft.  It was a great fit, but I would also be interested in the 915D3 since I have always favored a smaller driver head.   I am a 15 Handicap and would like to get  some advice on the proper loft for the 915D3  9.5 or 10.5 and keeping the same shaft.   My 915D2 driver is currently set from the fitting at A3.  Any advice on proper loft me on a 915D3 (440cc) would be great.  Driver swing speed low-mid 90's
