Part of your choice comes from what the track will be like. I ride a "converted" track, ex-kart track (New England Velodrome), with very shallow banking. Speeds are pretty low so aero doesn't count as much as snap (I may eat my words later but I used a TriSpoke/HED3 front in 2009, will use a less aero, much lighter wheel in 2010). On a track like the one I ride a stock bike would be fine (I'm partial to the Jamis but that's just me).

Use a non-QR skewer and you should be able to use a road front wheel, and since that's the wheel that really counts for aero, you can do that. I bought a set of non-QR skewers and plan on using my main (racing) front road wheel on the track.
