Turnabout945: Has anyone compared these two yet?
I have been playing the level 80 R9 for months - the new level 81 G20 Driver is much easier to ding and far more forgiving AND precise. The meter also does not 'zoom' past the ding as is typical of the R9 (and R 11 3 wood for that matter). I have purchased the set (a bargain, even if you toss the hybrid) and all speeds match.
R9 is maybe a tad longer into the wind but the G20 is within a couple yards (even into the wind); it will easily average 300 yards - here is the important difference - IN THE FAIRWAY.Sell your i-15's and get the set.
