I run a TF in both autoX and open track. I like it best for autoX, but works fine on open track also. Watch my videos for downshifting to first on tight turns at Thunderhill West. I am running 3.23, and run first gear most autoX courses, and 1-2 at Thunderhill. Two feet, two pedals= just right. Search norcal-fjo on you-tube. Have fun!
