Depends on what you define to be "fast enough". The Denso motor has a free speed of 84 rpm's. If we assume the rollers will run at that speed (ignoring friction in the system), with a 2 inch diameter roller, and belt on both sides (ie sandwiching the ball), thats a travel rate of about 8.8 inches per second. For our system specifically, this simply isn't fast enough for us to be competitive, but every design is different. Looks great 842! Teams like you and 1726 should get special recognition for the openness you both have with your design process.

PS. I realize you did get the 2008 Chairmans Award, which is pretty good i guess , but maybe a ribbon or something would be nice as well...
