Check out the site : http://www.bicyclerollingresistance.com perhaps this will help you too. My weapon of choice for carving up the track are Schwalbe Thunder Burts all round, they are super fast and exceptionally grippy. Another excellent tyre on the front (and on the reart is the Hutchinson Python Gold. Super Grippy but hard to get hold of locally. Your best bet is chain-reaction cycles for this. The Hutchinsons are significantly heavier than the Schwalbe's though. In my opinion the Thunderburts all round give you the best compromise between speed and grip. It's way grippier than it looks, you'll most likely run out of confidence before the tyre runs out of Grip...
