As Jon said if we had more people and started at normal time we could easily get between 6-8 rounds so you could do 4 to count or something, would really appeal to people that way i think!
Yep i'm up for it again anyway!
I know it depends on Numbers but i think if you had 8 to 10 people and then did two line starts it would make it even better and probably a bit less carnage at the first corner - plus it stops the front row hanging back trying to play it safe
