Was fitted for a 910D2 at local Golf Galaxy. The young fitter exxentially matched my current driver performance to a D2 with the Kai'li shart in Reg flex with my current driver. Per launch monitor I was getting similar distance with an improvement in spin and dispersion (more accuracy). Same results with a 910F 2-wood. Bought both. (D2, 9.5 deg and 3-wood 15 degree) Went to the course and guess what? I'm losing 25-30 yds in distance on both. My swing speed is in the low to mid-90s. was getting 250-260 yds with my former driver (FT9 with reg shaft). Now getting 230-240 with the D2. Am more accurate though. Last round had the club set at the D4 setting and was hitting generally straight or with a slight draw.
My thinking is I may have jumped too soon with the Reg Kai'li shaft. May need to look at a stiff shaft, either the same model or a different offering. I'm 58, 5'10", 160 lbs. Don't think I'll get stronger as the years go on. Currently playing to a 10+ handicap.
I have my doubts about the quality of the fitters, both at the Golf Galaxy and another location I went to yesterday. At this other place the "Titleist Trained fitter" told me at the D4 setting the face was open. Previous discussions on this board indicate as the loft is increased from A1 to D4 the face goes from .5 deg open to .5 deg closed. I would expect the "Titleist Trained Fitter" to know that. Tell me I need to find a different place to go. Unfortunately, haven't found a Titleist demo/fitting day anywhere in the state of Virginia. Maybe later in the season.
