Funny you mentioned that, as I just finished having a discussion with someone about that. A really cool concept to have the red eyes be low launch, and the gold eyes being high launch. The guy I was comparing with just finished demo'ing the Speedline 9064 with RIP gamma and loved it.
I was able to hit the gamma and it felt awesome but the numbers were too high. It was a 10.5 and normally I hit a 9.5 since I already hit a high ball. I think the gamma in regular flex and 9.5 would be perfect for my swing. I also heard the shafts are the real deal too, not a made for OEM RIP but a true RIP just like if you were to buy it after market. Sure felt nice.
