I ride Mavic Ksyrium SL for training, and just got a PT with an open pro wheel. Judging by looks alone, especially when put next to my egg beaters, I don't trust the open pro for a whole season of training, pot holes, small vermin, etc...

Saris has a list of compatible wheel sets on their web page. I race on ZIPP 404's, but, don't want to ride them for training. I am leaning towards HED Jet 50's. Pricey yes, but, should be pretty bomb proof. You may consider as well Flashpoint's, made by Zipp, but, less expensive.
