With my erratic work schedules I have not been able to participate as much as I used too, but for my two cents worth, I am in the GAR camp. I enjoy the simulation aspect where the cars are running on as close to what they would be running in real life. Tire choice certainly would not keep me from participating though. I like the approach of the fastest guys here setting lap times close to what is being set at the specific track in real time. It brings even more of the Sim aspect to the game. I have'nt mastered much of this game but ungluing tires is one of them!
