That is kind of why I asked the question. I see guys with .21 pitting anywhere from 7 to 11 mins. I normally come in at 8 to 8:30 but I still have fuel in the tank. I run in the B mains right now and it is only 15 mins so I stop at 8 to refuel.
Really just wondering why everyone prefers .21 over .28 that's all.
