Are you competitive on the track, fighting for podium finishes? If not, bladed vs round spokes means nothing, and because bladed can be a PITA because you need to use a spoke holder while building, DB round spokes would be my suggestion. 24 radial front /32 2 or 3x rear. If you're really riding on the track and only good days on the road, aluminum nipples; if you ride streets in weather, brass nipples.
