Basically, my reservation for the OP's is the reviews they've been getting on Roadbikereview: people call them out for making a creaking noise after a few months, and some have cracked them between the eyelets. This is disconcerting.

My reservation about the Aeroheads and reason for considering the OP's over them is that in the past I've been told by bike shop employees that Velocity uses a weaker aluminum than Mavic in their rims.

I wonder how much truth is in each of these statements.
