Thanks! Will have to keep an eye out for this one. I went with the Reebok ball, it was only $30 but felt much, MUCH nicer than all the other balls I tried. Unfortunately I didn't come across the Wilson Evolution.
I did get to check out the Jordan Champion ball, but like most other Nike balls, it felt slippery even when deflated! Couldn't get a good grip on it. Fantastic design on it though.
I think for the money, the Reebok is probably the best bang for the buck.
