Re aero,
my test is a riding buddy who outweighs me substantially, and always would coast past me on the descents.
When I got the Easton 60mm wheels, it reversed. Later he got a new bike w/ deeper wheels and it became more even.
Just recently one of those wheels fell apart and last weekend he was on the old bike (Spec Roubaix) w/ the alloy wheels, and I once again coasted past him on the descents.
