I weigh 240lb and 99% of my riding is commuting so the aero properties of my wheels are a much lower priority than their ability to survive the untold abuse of riding down stairs, jumping curbs, glancing off car body panels, hitting big potholes, and occasionally getting caught in the train doors as they close. I'm not gentle with my bikes either, I like to hammer thru the urban environment.

Deep-V rims are pretty good for taking abuse because their triangular-ish section is an exellent design from a structural integrity point of view. The fact that they may be a bit more aero is just a happy coincidence for me.

As for speed, when you're wearing street clothes and hauling a full mes bag on your back, a few ounces of weight either way or the profile of your rims will be totally insignificant.
