Whilst I fully understand the preference and need to keep things as balanced as possible numberswise, the thing that makes this works is the "Team" thing.
It"s well documented that Luton have been very active and successful, (the 2 don"t necessairly go hand in hand) in recruiting players and this should not be penalised.
Therefore I suggest the following.
Luton, West Midlands, Liverpool and Solent remain, as they are the largest teams and the smaller teams are asked who they would like to "pair up" with, if indeed they want to at all. I have to say a Stockton/Sunderland team, whilst being a fantastic one to be friends with, would be a hell of a force at the bar, let alone the tables!! Just imagine Craig (Johnny Bong) and Stuart (Fatcatstu) together with Katos, ShortstackAl, PhilTC and the Stockton Rock (mind boggles).
My hunch is that we may well find that most players are fairly happy with the team they are in, but this suggestion allows those that are not, to at least give themselves the opportunity to become part of a larger team, without destroying their own.
