Hi John,
I'd like to see some incentive for teams to go past the fifty yard line, if you don't want to add more electronics then a flag in the centre that scores a bonus if it's taken to a position in the oppositions half would be good. Doesn't need to be at the end of the game either I think better if it can be done at any point. A successful 'flag hang' scores a bunch of points.
On the back cans topic I think people need to remember that they aren't meant to stay in them, they just stop teams getting trapped at the gate and make it easy to spread. Too many teams are staying on the back line, they'd have more success and the games would be more exciting if they push off that line.
Just my thoughts! Love the events John so thanks for your efforts!
