You must have had bad bearings. There's simply no way a properly made, sealed ball bearing would produce more friction than a plastic bushing. The Igus stuff is great and has a lot of useful applications, but for drivetrains ball bearings are still the clear obvious choice.
How are the Banebots hubs otherwise lighter? Is it just the smaller wheels reducing hub diameter?

Speed has very little to do with wheel choice. In terms of pushing ability they are a step below nitrile tread, but compare favorably to AM and Vex kit wheels and are pretty close to gum rubber rough top / AndyMark tread. If blue nitrile has a CoF of 1.4 and other rough top has a COF of 1.3, I would put Colsons at about 1.2, before factoring in tread patterns.
