One of the fastest tested front wheels for a track set-up is the old Gippieme 16 spoke aluminum deep dish with a 19mm tire. That's on a wooden track with a high pressure. I can't remember who did the actual test, but it was a close second to a Zipp 808 set-up. That Gippieme is probably one of the narrowest wheels you can find now, with everything having gone wider, toroidal, bulged, etc., so that really says something about being able to cut down your frontal area on tracks that have a smooth surface that already sorts the rolling resistance issue for you.
