My rear wheel (Bontrager Select) started showing stress cracks at the spoke holes, and was getting squirlley on me, so I headed for the LBS. They had a set of Mavic Equipes on sale 30% off, and I picked up a pair. They feel pretty good, so far. Haven't noticed any speed difference, but I haven't had a chance to really give them a workout, yet.
They're a little lighter, and the rims are a little deeper, so they may be a little more aero, but I'll have to put some more miles on them before I can say whether they're faster.
