Tires?

[highwayracer]

Hi! I'm looking for your thoughts about the merits, or lack thereof, for different tire options.

I primarily run track trials and hillclimbs. Since 2006, I have been running IT7, which in SEDIV has a spec tire (Toyo RA1). I recently purchased an ITS car (The ex-Capaldi Mercury Cougar) and need new rubber. Having run the Toyo RA1 spec tire, I'm very familiar with the grip and feel of that tire. However, I know its designed more for longevity that speed. If you're not familiar, track trials are generally 20 minute sessions much as practice or qualifying sessions on a race weekend. Car runs 225/50-16. Tires I'm considering include:

Hoosier R6
BFG R1
Nitto NT01
Hankook DOT Racing
Yokohama A048

Any feedback you can provide, pro or con, or alternate suggestion, is greatly appreciated.

Thanks!
