I think there is good points both ways.
Shorter events Good
IC Only
7 min qual , everyone does the same.
The long finals is where the racing happens and improves your racing , so longer finals
If your a very average driver like myself you can be out by Saturday arvo , no Sunday racing at 4 day
There is no division of classes , PRO and SPORTSMAN.
Some of us will never make an A main final at a big meet so if the numbers are right why can't it be split into 2 classes ?
