I picked up this club at Golftown (I'm Canadian, and since in the end I wanted a brand new one I had no choice) after 1 round I noticed a huge improvement in my drives (lessons helped though!) but in comparison to my old driver which was a Callaway ERC. It's absolutely phenomenal. When I hit the sweet spot in this thing, it carries at least 250. Boy, does it sound beautiful. My ears ring for minutes afterwards.
This is one outstanding driver! Prior to owning this one I had the r7 460 and thought it was the cats mewow. I bought this SuperTri two weeks ago and have played 6 rounds with it, my average drive with the r7 was around 190-210 yds, with this I'm getting consistently 245-260, playing a Titleist NXT Tour-S ball. Not bad for a 63 yo, huh.
