I'm pondering picking up a used SuperTri off the bay. Just to mess around with. Mostly based on what I've heard about them here... Question: I usually play a 10.5˚ head on my driver, but I'm thinking about going to 9.5˚ as I've been seeing a little too high of a ball flight lately. Is there anything about the R9 ST that I should be aware of prior to grabbing one with a 9.5˚ head?
