I'm still looking at wheels too, and am flip-flopping between something like HEDs with Sapims and Cks, or the Enve 3.4 SES (the new version). Some builders have said 24x28 for my 177 lbs but heck...the DA C24s are 16x20 and are fine for most riders. I hope if I go Enves, they are faster than the HED/CK combo.
