Has anybody used this ball? It's an International SD-73, the specs are from the dark blue SD-73 and not the SD-73 Classic. The specs are RG 2.500 Diff .075 and the coverstock is Sure Grip Microtech, which I figured was a particle additive added to the Sure Grip that was on the SD-73. It's a real deep purple solid coverstock with MTX on the side! Thanks, Bruce
