Lets see... as I've mentioned in an earlier post, we used the six of the 8" KOP wheels (with SBR Roughtop conveyor belting on them) for budget reasons. They worked extremely well, we never came close to tipping, we got insane traction (although we did leave some rubber on the carpet during our more "spirited" pushing matches), and our ramp climbing was among the smoothest at VCU. (We didn't have to charge it or anything, just drove up it normally) For many cases it shouldn't really matter much, if your center of gravity is high enough that you need smaller wheels, then you have bigger problems. That said, I happen to think that those little wheels on 696's machine look really stylin' and am looking into Colson wheels for our drivetrain next year. (There are other reasons why small wheels will be desirable in a couple of the many drive configurations I'm looking into)
