Hyperon has better bearings, rolls better, classy looking as well.
As for the Ventoux, climbs a tad better, slightly faster on the flats, better acceleration.
As for all LW wheels, the Ventoux can be repaired if there's a damage (apart from the spokes of course).
Brake tracks can restored if it's worn out.
For daily wheels, I'll stick to my 32 spoke Open Pro with Campy record silver hubs
