I just ordered some Pacenti Forza rims from bikehubstore.com. They have a nice package discount with CX-Ray spokes. I realize that Pacenti had some cracking issues with their older rims but the Forza's have been beefed up and I like the idea of the offset rear. At any rate, that's the path I've chosen so we'll see.

The rims that seem to hold almost universal acclaim are the HED Belgium C2 & Plus, and the Easton R90 SL. There are other excellent rims as referenced in this thread too so the decision on what to go with can cause information overload if you are the analytical type. On the other hand it's hard to go wrong these days so...
