Novatecs are decent and will fit the bill for what you're going for. Gran Compes are also a solid choice (I have them on my bike for track and road riding, no complaints). And if you like purple, you could get these Soma hubs mad cheap: Soma Somax Track Hubset: 3DV Purple Ano - 36H - 120mm - Flip/Flop - Front/Rear (NEW) - Bike Recyclery -- I picked up a set for a future wheelbuild not long ago. Bearings aren't the smoothest, but they're decent enough.
