Par4QC I agree about the AVX. It was very short off the tee, and I've never seen a ball do that, except for the other you also mention; I find that a bit odd. Glad I only tried a sleeve of each.
I thought they were fine off the tee, but they just wouldn't check at all on chips and pitches. I don't see the point of paying extra for a urethane covered ball that's like a superball around the greens. On full(er) shots I thought the ball was fine, but so is the Supersoft at a much lower cost.
