You could go with the custom build that SadieKate and a number of other TEers have gone with (including me): Velocity Aerohead rims, White Industries H1 hubs, and Sapim double butted spokes. They'll put you back about $650 and will weigh in somewhere between 1400 and 1500 grams. Bring some extra spokes and nipples with you and you should be good to go. Mine needed to be trued once after they were "broken in" a bit. Since then, I've put about 10k miles on them over some rough roads, and they've remained true. They're wonderful wheels and the WI hubs have just the right amount of bling!
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
