Stay 700c. 650B is nice for the frames it is designed for and the little people who ride them. 700c is the current standard and there is no good reason to leave it.
Yes, I realize how big an overall change it would have been, and I guess I just got caught up in the 'do something different' fever. But you guys have convinced me to stick with 700c (and I agree totally that standardization is best for certain things).
So I'm going to try these 700 x 35 tires on my current wheels, and see how they do. If I eventually want to try wider rims, I'll take that step later (and maybe, hopefully, have time to build them myself).
