With mine, I'm inclined to change it to under 18s, because the competition is still dominated by the bigger clubs in the region (Villa, WBA, Wolves).
I'd like to do it based on best teams in region - it's not strictly speaking accurate, but it's not ridiculous either and allows newly created clubs to enter. However, it doesn't have a "professional status" filter. Maybe it's possible to create a secondary division which is auto populated with teams from a region ... will have to try that out.
