FWIW, I’ll throw out another review. My buddy, a very big component guy and lover of all things golfworks, bought a TC driver and a ST2, and the ST2 beat out the TC and his ping 410. He was shocked, but it wasn’t close for him. He really liked the TC - it was as long as ST2 and as forgiving - but the ST2 had better sound and was easier to turn over.
