Nohing wrong with a class for that....in fact, exactly what you are saying DOES exist and it looks like it will be a hit next year as well, Crazy 8's! Nothing wrong with running that class and you don't have to have much into your bike (at least compared to prostreet). Now, if we can just get that cone moved

....
There seems to be more bikes in prostreet than ever (well, maybe not ever, but at least it is on the up-swing again). Why would you want it to change now, people are ok with 6 seconds. I have posted in the past, a racer will do what it takes to win with whatever rules and limitations there are. If you are born to win, you'll win. Even bigger guys can win if they work at it, pretty much anyone can (within reason). If money is the problem, then bracket race. If you are good enough at bracket racing, more money in the next lane won't beat you.
Just go out and have fun. VERY FEW racers in any class or type of racing make money racing anyway. Work an honest job and spend a few bucks on the weekends to relax and have fun. If you race as a true hobby, it can be almost as entertaining losing first round as having a good day and going rounds.
