I'll add my experience with the caveat that what works for me may not work the same for you. Anyway, my Masi Gran Criterium S came with Easton Orion II's when I got it 3 yrs. ago. I looked into new wheels and was informed by this list that what I had was pretty good. So, I didn't bother to keep looking. I've used Vittoria CX's and am now running Bontrager Racelites. This is all with Dura Ace hubs BTW. Three years ago my riding weight was pushing 200 lbs and now I'm closer to 185 lbs. It all works very well for me and I'm sure I'll be running these wheels for some time to come. Here are some reviews of the wheelset: http://www.roadbikereview.com/cat/wh...x.aspx#reviews
