Titleist is the first to admit that the 907D1 and 907D2 - two drivers with near identical launch conditions but different looks and different MOI characteristics - were perhaps not the best pair of drivers for fitting a wide range of golfers. They've corrected that "one set of launch conditions" error with 909, offering three models: the composite-crowned (a first for Titleist!) 909D Comp, the "tweener" 909 D2, and a low-launch, low-spin, 440cc 909 D3.
It seems to me that Titleist's 909 drivers are the most eagerly awaited Titleist drivers since perhaps well in a long time. The retailers I've talked with are reporting good sales numbers, and PGA Tour adoption was awfully quick, with the majority of staff players switching before the first ball was struck in 2009. On a personal level, the number of emails, PMs, and IMs I've gotten from people anxious to read this review has been off the charts - and the 909H and 909F3 reviews only seemed to wet their whistles.
The 909 D3 Drivers eliminates the need for compromise in my golf swing. Ball flight and spin are well within the zone for my swing speed (~108 MPH). The ball comes off on a lower, flatter, more boring trajectory. I can hit the ball lower (in wind, on firmer turf) if I want, and I haven't lost the "carry the trees on the corner at the 10th hole at Lake View" shot, either (high ballflight).
The 909 D3 Drivers has the killer looks in my book. The 909 D3 Drivers is again 20cc smaller, and the difference is subtle, but noticeable if you look for it or set the two models side by side. By now, we've all adjusted to looking at titanium balloons on sticks, but it was very easy to like the looks of the smaller 909D3 over the D2, and to like both of those more than many of the other "we want to look really large" drivers out there.
