BillyD cut a lot of good info (along with some stuff that needed to go).
They suggested (at different price points): Velocity Dyads and Race spokes with either WI t11, CK r45, or 5800 hubs (28/32 on the first two).
I'm not convinced you need that heavy duty of a rim, but Psimet is a pretty solid outfit and they know their stuff.
I'm more in the 225 range and ride r45's with Pacenti SL23's (28/32; CX-Ray).
