I built a wheelset for our tandem, 286 lb. team. I bought the parts from bikehubstore . I bought 36H Kinlin XC279 rims, CX-Ray spokes, and nipples, and laced them to our Chris King hubs, which we already had. I built the set myself, but your LBS or local wheelbuilder could do it for you. I built the wheelset in January 2014 and IIRC, I've done a minor true a couple of times. We have over 6000 miles on these wheels. These are 23mm wide X 28mm deep rims. They are very strong. We run Conti 4000 IIS 28mm tires, 105 lbs. for us, maybe 110 lbs. for you. Never a pinch flat. We broke one spoke in a paceline accident, otherwise they've been perfect.

We're a little lighter than you, but I think this build would work fine for you, with whatever hubs you feel would work in your budget.

Edit: On the issue of one wheelset not working for every weight, I weigh 145 and built a similar set for my carbon road bike, same model rims and spokes but light hubs and 20H front, 24H rear. They look really cool and are fast wheels. Yeah, wouldn't work on our tandem!
