I'm about to build up a wheel-set. I only weigh ~150lbs and only plan to have ~30-40lbs of stuff on the bike when touring. I also plan to use this bike for leisurely and somewhat spirited summer rides, so I'm steering clear of the Surly LHT with big beefy parts sort of build. What would you suggest on the lighter weight end of touring rims? So far I've read good things about the Velocity Dyad and they weigh less than a lot of typical stout touring rims, but I'm hoping there's something that isn't going to cost me $75/rim. Under $50 would be Much preferred.
