I have Mavic OP laced to Phils for my clincher wheels. They are very strong but a bit heavier than my tubular Mavic Reflex hoops laced to high flange DA. (Both sets 32h 3X)

The popularity of Deep V's must be a style thing (as they come in colors; they nailed the FG market didn't they?)Deep V don't even have ferrules for the spke holes which allow for more even spoke tension and stress distribution.
