I've got 3 sets of CXP 33. wheels. Stronger and stiffer than the open pro.
The weight penalty ain't that big. I weighted one of my rims to be just below 460 grams.
That's less than 30grams more than open pro (averages at 430)
Using Shimano hubs, 28 is not really an alternative (aero only).
With a low profile rim, I wouldn't go anything lower than 32 spokes.
