I never have too much remorse or regret. If I've moved clubs on its because I believe what I was getting was going to help. Some did and some didn't. That's the gamble of buying new gear. Those Cally fairway woods though were simply the best ever and I've never found anything to match them
I'd second this as one of my biggest errors.. I bought the G20 driver and 3 wood when they came out.. Driver was to replace my Nike that shaft snapped on. The G20 was exceptional as a driver but the 3wood was phenomenal I've never found a club as good since.
