i think the good rims to use would be some gp4 or montreals. i hear that the ambrosio nemesis are supposed to be really good.

on my daily ride for the last 7 months or so, i've been on some old saavedra turbos, 36 holes, with dt competition spokes 2.0/1.8, laced 3 cross. the rims don't ever see a caliper so it's ok if they get a little wobbly, but they still roll smooth. i think that's a sub 300gram rim and i weigh 185lbs and am usually carrying another 15 pounds in my bag.

lace your rims up good, avoid the nasty potholes and you'll probably be fine with any of the rims mentioned in the replies to the list.
