Ive recently been experimenting with an 03 Tour MP after about 1.5 years of dedicated play with TF335s. I have no other experience with sub 12 oz frames. I'm enjoying the lighter swing weight in the second hour of play, I'm definitely getting more power on 1st serves, and don't have any negatives, except a little more arm shock that I think can handle. Does anyone with O3 experience have other alternatives to suggest before i go out an buy a few more? my game: 48 y.o., between 4.0-4.5, 1HBH, lots of topspin, good kick 2nd serve, finish points at the net.
