Track day: FP, SI-1 or race gas?

[00 scrub]

I'm heading out to a track day soon and wanted to make sure I kept my detonation/timing retard down. My car has variable valve and ignition timing and the computer will reduce timing if it detects too much knock. I was wondering if Fuel Power, Redline SI-1, or some 76 100 Octane race gas (a gallon or two) +91 Octane (what the engine requires normally) would be the best bet to do this? I'm using Redline 10w-40 street oil for the engine.
