I promised myself a nice new set of wheels once I upgrade to cat 3, and that time has come! I've narrowed my decision down to these two choices. They're virtually equal in weight, so that's not an issue. What I'm wondering about is which is more aero. The 303 is 38mm deep, and the DV-UL is 46mm, but the 303 has that "regenerative air foil" that makes the rim look deeper to the wind than it really is. Is this just hype or is it true?" The other issue is the bearings. I know Zipp is known for having ultra-smooth bearings. What about the Reynolds bearings? Are they just as good or better? And finally, anybody that would like to share first-hand experiences with either (or both) of these wheels is really appreciated!

I have a pair of 404s and a rear 303. The 404s are much more aero than the 303.

Go deeper young man!

you mean the plain old Status DVs? the DV-Ultralights are close to 2 grand.
I'd get the Stratuses. White Ind hubs are known for their reliability. I had a pair of 303s, and never really felt that aero (subjectively). I have not, unfortunately, ridden my Stratuses yet.

What about the side to side play in the White Ind hubs? A friend has a set and he said that he contacted WI about it and they said it was normal. It just seems kind of weird to have that much play.

... What I'm wondering about is which is more aero. ...

Notwithstanding the Zipp "regenerative airfoil" the 46mm DV is more aero.
