I wouldn't go Velocity Deep V. Two LBS's I frequent warned me away from them (I'm a 255 lb clyde also).

The thing is, they're known for cracking by the eyelets, especially for heavier riders. The rim is actually narrower than the width of the nipples at the apex, and it's a weak point.

I'd go with Fusions instead, if you want that deep V shape. They're a bit less aero, but stronger.
