The head pro at my home course has a hard-on for Nike... I'm pretty sure he's getting a kickdown.
That said, he had the Nike rep out for a demo day. The range was closed for maintenance, so he setup shop on the 10th tee box.
Long story short, I was mashing that thing. I play an R11, 9* lofted up to a little shy of 10*, regular flex. I had him set me up with something comparable so I could get an apples to apples comparison. Now granted, there was nothing at stake and I was laying into them, but I'd say I was easily getting another 15 yards out of that cavity back atrocity. I then had him switch it up to what he thought made sense based on the launch monitor, and although I don't know that it added any more distance, I was able to work the ball significantly better than my Taylormade.
Honestly, I probably would've picked one up had my woman not just dropped the cash on the R11 as a Christmas gift. Not sure how I would've explained that one :).
