It really depends on your budget and how bigger weight weenie your husband is.

The Mavic Crossmax's are hell bling and roll very nicely. There is not a big difference between the SL and SLR models, so I would go the SL's if I was buying them on their own.

If money is not an issue and you want a lightweight set of wheels I would get DT Swiss 240 hubs with Mavic XM819 rims. But you can go for a cheaper hub which will reduce the price a lot.
