I really like Capcom/Coors bowling trackballs. They seem heavier than normal ones.
I have the PS2 version of the Imperial trackball above. It is pretty nice. Got it new in box on ebay for $30 or $40 a while back.
I would rate it as having a better feel than my rebuilt Atari trackball (Crystal Castles), but not as nice as a new Golden Tee trackball.
I see that coors bowling kit is on a Pac Panel. That was the best cabinet for that game. (The one I used to have was in a Pac-Cab also).
