FearlessAl: Would it be worth the money to go ahead and buy the R9 at this point or would it be better to save the credits for the level 88 R11 and just live with the G10 for now?
Given he time it's going to take you to get to level 88 I would go for the R9 now (heh-easy for me to spend your money.) There's a lot of golf between you and that R11 and IMO the forgiveness of the driver and the added distance will benefit you in the long run.
The G10 has a higher trajectory than the R9 so will be more susceptible to the wind which is probably why the R9 consistently outdrives it. From your tees that difference in trajectory isn't a huge deal. It is from tees farther back. The extra forgiveness of the R9 is helpful if you're inclined to miss the ding or aim by missing.
