glad to help birdfeeder. Kolpak players were a real problem until the rules changed. Even at my level (wepl) there are ex-internationals and other overseas on 1k plus bonuses a game, it's getting ridiculous.
I think that as Birdfeeder refers to counties he is asking about County Cricket so the only leagues/competitions will be the county championship, the Yorkshire Bank 40 overs and the Friends Life T20.
I've noticed some counties seem to have 3 overseas players in some games, although maybe some are South Africans who come under 'kolpak', and maybe some others have been here so long they now count as non-overseas
