Oh yeah, if you do run Presta valves on your Deep-V's, you might want to think about either long-valve tubes or valve extenders or something. I have Conti tubes in my rims right now and the Presta sticks up just enough to "lock onto"... but the pump has to be perfectly straight, heh.
*edit* I guess the same would go for Schrader valves too, I never really thought about it.
