I've been having some swing changes. Formerly used a reverse tilt with an early cast. The 912 AP10's were fitted with the A-Flex AD-65 shafts, and was fitted for a G15 driver 12 degree. I now use a 10.5 910 D2 with an Ilima R flex set to 9.75 (trial and error). My 6 and 7 irons now go as high or higher than my Volkey stock 48 degree GW, then drop straight down.. Driver speed has gone from 80 to 88 mph, and apparently the 6 Iron was clocking 82-84 mph at the same time and launching around 22 degrees. The driver was launching 17-19, so that's when I moved it from 10.5 to 9.75.
Can I expect that I will need to get refit and what shaft(s) would be a good starting point? I'm open to steel as well as graphite. Since they are 18 month old 912's, I'd prefer to re-shaft if possible. When I go for a fitting, I've already priced the Diamana + Blue 62 if the fitter wants a lower launching shaft rather than dialing back the driver head as another starting point.
