Double eyelets are generally good things, all else being equal. However, the Velocity Aeroheads have proven themselves to be at least the equal of the Mavic Open Pro, and probably better.
Velocity Deep V is a very durable rim, aerodynamic, but heavier. It's used by urban riders frequently, not really a light-feeling rim.
I would again say to go with ovalized spokes instead of bladed, so you don't have to worry about getting them through the hub. (Although some bladed spokes will fit through the hub flange.)
