Sherif I used a Prince calfskin, i'll report back with my thoughts... I see you also play with the 4d200 16x19. I just picked up one of those and it seems to offer some things the 320 vo2 does not (most noticeably a more "solid" feel at impact), but I just cant decide which one I like better. Both are great sticks, just totally different.
