dphatt I totally agree on the Mavrik being more muted than the Epic Flash (I like it better actually). But, the Sim was TOO much in my opinion. I was hitting the Sim 3 wood last week for the umpteenth time to talk myself into getting one and the fitter kept telling me my distance numbers and I couldn't get over the fact every time I hit it, even though I could see the ball flight, it felt/sounded like I was duffing it. Hard to explain, but the feedback was just terrible IMO.
