Well read this and let us know what you think:

I think the concept of aero wheels works, but in some cases you'll find a deeper dish wheel in the rear and a shallower dished wheel in the front, technically this is backwards because the air that rushes at your bike hits the front end first then it gets all dis conglomerated as it gets back to the back wheel where a deeper dish wheel does little! Of course a deeper dish wheel in the front may cause some handling issues in cross wind but as long as the front isn't over 50 to 60 you'll be fine, so you could use no more than 50 to 60 in the front and a 30 in the rear. If you're deadset on the Mavics you can get a far better price for the same wheels on the internet. The problem with the older Mavics is that you have to send away for new spokes and then they changed the design so the spokes for the old design became increasingly difficult to find to now all but impossible to find, I'm not sure if the new Mavics can be fixed with off the shelf parts, if not I would stay far far away. The Mavics are not that deep of a wheel, if you want a nice wheel set that is similar to the Mavic Shimano Dura Ace makes a good one and with labor day looming sales are on and this is the best price I could find on those:
