Re: Colson Wheel and AndyMark HTD Pulley

Honestly, I'm not seeing the ground clearance issue with the belt; if that were a problem, you wouldn't have people running VexPro 72t gears direct-mounted to 4'' omni-wheels, which I have seen work with no problems. Besides, if anything contacts, it'll be the flange, and given the near-redundancy of a flange in this setup anyway it's not exactly clear that there are any real wear issues with that.

Also, while it's nice to keep the traction wheel in a butterfly drive small, 3'' isn't exactly "much too big" - I've seen teams run butterflies with two 4'' wheels which worked fine and weren't particularly heavy.
