Jeff,

I was on old Hoosiers friday and turned a 121.2. On Saturday and sunday I ran on what started as 1 heat cycled goodyears and ran high 21's and low 22's. I was not consistent on the goodyears as I struggled to figure out rear end grip and therefore made lots of mistakes resulting in inconsistent times. I even spun on my own in 3. (Friday was very consistent low 21's) I ran the street tires on the test weekend we had and ran a 24, that same weekend I ran a 22 on the same hoosiers i used this past friday. Street tires are cool for long races eliminating the need to swap tires but in Sprint races unless everyone is doing it... don't!
