I don't mind the way it is, I like USAC's format. Sometimes it's frustrating if you it breeds a lot of cautions in the back but it seems to me the guys in the front of the heats were having as many issues as the ones in the back. I like the way the heats races are loaded, it gives it a "big race" feel on Sprint Week. If you have too few cars then the heats turn into virtual hot laps and there is less opportunities to pass.
