LOL, yeah, I was just looking at the gorilla stuff and I already have the urge to get on ebay and find me a Revo roller.

Anyway, I just used the calculator and it appears that around 8 pounds of load is the max for an L can motor. I think I'm going to play it safe and go with the XL. Runtime or no, I can't have the thing over heating on me. Besides, the 7XL appears to be able to get me to 40 with relatively mild gearing.
