Last night I got to hit 5 shots with one. Super smooth shaft (gloveless mind you). But the hit feels hollow to me. I really didn't try juicing the ball much so I'd like to try one out for a practice session or two.
I had two R12.9's for a couple years … just switched to the Cynergy which I like better. But its all subjective... if you can, try out a few different ones before buying.
I got a flyer from the Predator booth at the US Open in April, it says:
