I agree that it should be one set of rules for everybody but where do you start!
Whatever you propose some will agree and some won't, it will never be a level playing field and can never be!
When I moved to Essex there was i guy near me that only kept 12 oldbirds and had won far more in the club, fed and combine than most ever will dream of agains many big team flyers.
What ever limits, restrictions you put on won't make poor flyers any better, only they can raise there game to compete but in most cases they would rather run away and form an inferior club where they can win a club card or 2!
