tires for race school

[FrozenInCND]

What would you guys recommend for tires for this weekend’s race school? Right now I have a set of slicks (Bridgestone) on my bike, with the weather being as cool as it is should I be changing them to my street tires? I rode them the 2nd last track day last year and it was about the same temp, but I had them on warmers and rode them hard enough to keep them warm. Any suggestions would be great.

Street tires will certainly work better, given the cold and stops & starts, but if changing them over is difficult then be careful on the slicks. If it's easy, switch em.
