Agreed with a lot of your points Ben
Although in saying that if rally experience is required to enter - where can someone gain this experience? It sort of sounds like "you must have experience doing rallies to do your first rally" So that makes it quite hard, almost impossible even to enter as a first timer. The modified class, as mentioned, means the entrants wouldnt be in the running to win a place at the end so wouldnt that discourage guys from getting every last bit of speed out of their cars as the risk of binning it is too great? Who would give it 110% if you couldnt possibly win due to rules, and stack your pride and joy in the meantime
The last thing anyone wants to see is a stack. Maybe more chicanes can be introduced to lower speeds at some of the higher speed areas, surely that will help - not that no one here didnt think of that already
