Glad you had fun, I got the track promoter to start flat tracking quads 4 years ago. First year all the guys ran knobby fronts but we had to run hoosiers or something equal in the rear. The first year was the best cause we were out there having fun. Then the next two years I raced my quad was like you said the others were slammed to the ground sway, hoosiers all the way around. It is a blast to do but it will get expensive if you want to be competitive.
