Gotcha. They sound like they will be a very nice build. I'm not in the loop anymore on spokes but know that many of the popular builders go with Sapim Laser or CX-Ray's. No need for a bladed spoke so perhaps look into what differs from one brand to the other. I've heard very good things about the rim you're looking at, take a gander at others like Velocity, kinlin, etc.

I just bought some wider rims for training and a Fondo that I'm doing and can tell you that the wider track coupled with the change in tire profile probably made one of the nicest differences I've had. great way to go!
