I've found both balls similar off the tee. Both hit an equal number of GIR's, with the ProV1 usually a couple of feet closer. Around the green, the ProV1 checks up nicely and gits-ur-done. Putting, for me, is about feel, and again its the ProV1. But, if have to give the ProV1x its due. For workability, their hasn't been a ball to compare to the ProV1x since the balata Titleist of the early 1980's. -------Thank you.
