You might think about Velocity rims. I'm not sure personally about the touring rim they offer -- it appears to be a deeper vee than I would prefer in a cross-wind. It is wider, however, than others in their road range to accept a wider tyre (probably up to 45mm).

I have Aeroheads on my randon bike, the off-centre one on the rear (delivered as a complete wheel with "Velocity" hub). I like. They will also be used for loaded touring. They accept a 28mm tyre and probably a 32 (I have yet to mount TT2000s on them).
