Sounds like a pretty good solution to me. Not first choice, perhaps, but pretty workable for now.
Just out of curiosity, now... so, you bought three rims, and built up three wheels. Did you buy three tires, or four?
All three built wheels have the same 27-inch Kenda tires on 'em, and I have a fourth matching tire.
I know, the whole thing is kind of ridiculous--no reason why it should matter, but for some reason it does. Oddly enough, I have no qualms at all about going around with mismatched socks.
