My Initial Thoughts
Firstly, we have to decide whether we want another tournament series running besides those which are already established.
If the answer is no, then it would seem sensible to unite behind Wendy, who currently is the dominant organiser in the UK, with a proven track record of organising events at all levels, and who has strong ties with the Millennium.
Since Wendy already has Midland and Southern series up and running, it shouldn't present many problems for her to organise a Northern league, all using the same rules.
The top teams from all 3 leagues could then play off against each other in an annual "Cup Final" event, and awards presented at an end of season party.
If the answer to my first question is yes, and you want something new,
then the first step is to elect a board to run the new series, so players can have a voice via the elected board members.
(I have taken this to be my first step as I am assuming Robbo already has sufficient industry muscle assembled to support a new series).
Personally, as I believe that skill doesn't depend on the amount of paint you shoot, I would then suggest that if cost is an issue for players, the events be run as limited paint, similar to the old WDP Forest National events.
I would assume that the majority of readers will disagree with the above paragraph.
Divsions would consist of pro, semi-pro, am & novice teams, with no roster locks, as then you have the excitement of playing against the pros coupled with the lower ranked teams being able to recruit pros to their own squad.
There would be monthly (or bi-montly) events at a central UK location, with independent refs - no teams reffing.
Standings would be calculated after the season's events and everyone attends an end of season awards party.
Personally, I would like to see monthly limited paint events at city centre locations throughout the UK, to bring UK ball out of remote locations and into the public eye.
