What should I look for in choosing wheels for a road bike?
If you're doing mostly commuting I'd look for strength above light. Go for something with more spokes and with a 3 cross lacing pattern. You want something that is reliable. Of course you weight is a consideration so there is always a trade off between that and durability.

Going with something with radial (straight) lacing up front can save weight and you're less likely to break a spoke on the front wheel so there is less chance that durability will be a factor.
