I'm currently riding Boyd 50mm carbon clinchers, bike is a BMC Pro Machine with full Force groupset. Bike came with Mavic Aksiums which were actually a very solid wheel durability wise. I sold them as i had better back up wheels from my previous bike. I'm 5'11, 150 pounds. The Boyds are very good wheels, hubs spin forever and they have been true since the day i received them. I go over some pretty rough roads here in LA and hit the occasional pot hole at speed and wheels are still perfectly true.
Now as far as the aero benefit i can feel it at higher speeds. I can maintain a 23+ mph tempo on my own longer than i could with the Aksiums.
