I've been running the Takeoff 27 and 32 this season and some Sorex 28, 32, and 36. I seem to be getting better results with the Takeoffs this year, so far the Sorex tires have seemed prone to overheating and blistering while the Takeoffs haven't. My lap times are also consistently a bit faster on the Takeoffs while the car has been easier to drive too. I've only been running the pre-mounted 27 and 32 Takeoffs, so the included insert is what I run. So far, I haven't felt the need for anything better.
