you sound lucky lol your roads must be a lot better then Chicago roads lolI have a pair of good double walls made by Vitesse that hasn't given me any problems at all. i have a 66cc china girl driving the rear one, and even with damn near disconnected spokes (several more than two or three i might add) it never went out of true. single eyelets, 16ga spokes, and 32mm valve stems, so about a 13mm deep double wall rim. this is, of course, a 700c rim, so a 26x4.25 rim is going to need a bit more, but vitesse won't steer you wrong if you can find that size.
