haha... yes I know all these clubs
London is generally covered by 2 leagues, Surrey and Middlesex. Middlesex has County League where Ealing and Acton are, below that a second league called Championship. Of the two league you need to be in County.
These are the top clubs with good players(a lot have ex pros), Championship is the rag end of the two Leagues. That's where I am
Ealing are the strongest team and have won the Premier League a few years, although not last year. Ramprakash turns out in the County League for his club(he was 160 not out batting 5 against Ealing last year-some of our guys watched him and it was different class)
So you get good players in County.
In the Surrey leagues it's further out but nice grounds, might be more travelling.
