So you don't have to spend on more experimental saddles than you need ...
Track is surprisingly hard on your butt. Road riders think it must allow you to ride the hardest nastiest saddle on the market, but the combination of rough tracks, hard transitions, much harder tires, stiffer frames, and the G-forces pushing your butt down onto the saddle in the turns makes tending to your derriere a necessary consideration. Just try racing a long very fast points race at Alpenrose. Ugh. Many riders like to stick to Rolls and other traditional saddles. Flites are very common. Because of the extra pressure exerted on your rear in the turns, saddles with cutouts can really save the day for some riders. You'll see some Aspides and SLR's and the like, but not too many and many are under newer or younger riders. For your first bike, you're probably better off going to a more substantial saddle than to an ultralight one.
