I wanted to get some feedback on a build I'm about to do. I recently purchased a Powertap Pro+ 24h hub that I'm going to lace to a DT Swiss 585 rim. On the Cycleops manual it states to lace the non-drive side with a 2 cross pattern (fair enough) but also says not to attempt slotting the flanges for bladed spokes. I'm definitely not experienced enough of a wheelbuilder to start messing with the flanges, but does anyone know if DT Swiss Aerolite spokes will fit through the flanges without slotting them? I've seen plenty of Powertap builds with aero spokes, but maybe they were all made after the flanges had been slotted.

I'm fine using round spokes if necessary, but would prefer to use aero spokes so long as I don't have to do any slotting or filing.
