A lot of very interesting veiw points on the subject. My tuppence worth is, F4+F5 10.5t no timing
F3 10.5t with timing allowed
F2+F1 Anything goes
The top 8 drivers, regardless of formula after qualifying to contest the A main. The next 8 drivers to contest the B final and so on. This would guarantee a good mix of drivers in each final. No marshalling issues either this way. Keep it simple lads.
