If they like the rule, they'll just change it so the top 9 (or 8 if no Workington) riders get split up, one per team.
I'm pretty sure 8.00 was chosen as there were 9 riders above 8.
Next year could be, each team picks a number one from this list:
Pickering 10.39
Lawson 9.25
Wright 9.11
Masters 9.01
Klindt 8.81
Thompson 8.72
Jeppesen 8.45
Cook 8.39
Harris 8.29
Then if Klindt & Cook don't want to race in the Champ, add Howarth (if he comes back),Nicholls & Kildemand to the list, if Nicholls retires, then Flint is next in line.
Could make the rule, no-one can sign a second heat leader, till every team has a number one?
