Rain Man Like you the big bertha was fun but I duck hooked it badly.
I had to hit it outside in to hit straight I then hit it high lost distance.

My boys and I each play a Callaway Ti 454. My oldest son did a 5 club driver evaluation a few years ago. He compared his gamer KZG RBT/325 vs. 4 other heads in the 400 cc to 460 cc range. One head was from the tour van, a rare prototype TM 540 9.0* built for Mike Weir. It was the worst head of the lot, its dispersion was real wide. All 5 drivers shafted up in steel then the best head reshafted to graphite. In the end all heads rated 5 to 9.5 considering accuracy, distance and trajectory. The winner for my son was the Ti 454. He hasn't hit a different driver head since. Compared to the 325 cc head he gained 25 yards and with a change of ball to the Pro V1x he gained another 10 yards on his average driving distance. Not bad, 35 yards gain in distance over a couple of trials. He has this driver duplicated in case the gamer ever breaks.
