More classes = more fun?
Overall you'd say yes but the time it takes to run events with all the different classes, the events just become too long. (it's an arguement many have)
Spare weekends, rain outs, just not enough weekends.
If you just keep including more classes it will only be a matter of time until there is a cap on numbers, or you would have to qualify to race at major Title events so they can be run in a decent time frame. Maybe we ultimately run a "A" division and a "B" division Title.
