Are you just buying the rims and building wheels with them or a pre-built set?

DP18s are decent for the money but they're heavy (687g claimed but it's probably higher).

In all honesty, unless you're getting a screaming deal on a complete wheelset I think you should spend a few extra bucks and get Velocity rims. Deep Vs weigh in at 520g and Fusions are only 475g (actual weight on my shop scale) if you still want that deep look.
