I had been gaming a Epic Driver that was custom fitted at their Carlsbad California headquarters. In the last 3 months, my club as had demo days for all the Major brands.
None of them performed any better than my current club. To a man, each rep said to keep my current stick.
Until Ping showed up. I gained maybe a couple of yards, but my dispersion pattern was WAY tighter. This thing is sooooo forgiving. Most of my hits are past center line towards the toe. Distance isn't the big key to me. It's keeping it in play.
