The Vuelta Corsa SLR is only $270 for the set and was 110 grams lighter, was there something wrong with the SLR's that kept you away from those? I would have thought the Cosine's at Wiggle would have been a bit better due to a more aero profile wheel with the same weight as the Corsa SLR, so you would have the lower weight for climbing and the aero for flats and downhills, and the Cosine's have a 4 pawl rear hub which means the force load transmitted to the hub via the chain is less with a hub that has 4 instead of 3, which supposedly in the idea world where everything is equal should make a 4 pawl hub last longer.
