Bought one. Had a demo XR16 in my bag for a month and was sold on it, but waiting for the Callaway & Titleist demo days to simply try out some of the other stuff, just in case. Myself and at least 3 other guys I know ordered the Fusion either on the spot or afterwards.
Everybody's swing is different, this club head and shaft combo just seemed to work for me. Distance isn't much different from anything else I've hit, but accuracy was my priority. This club gives me reduced back spin, better roll-out, better dispersion (especially on mishits), my misses don't go as far astray, etc, etc, etc. Launch angle is hard to say. I hit this 10.5 degree lower than my other drivers, probably about 13.5, yet I've loaned it to a couple of other guys and they tower the ball (probably about 16 degree launch). One of them now has a Fusion demo in his bag and is highly likely to buy it.
