Currently in Vanerama League South, works wonders, just make sure you have quick central defenders, the full backs push up and move into the middle when you are near the edge of the opponent's box and long ball counter-attacks can burn you.
Also, find a good set piece guy, makes all the difference in the lower leagues. Striker/AMC isn't a big deal, quick DCs, good dribbling ML/MR and a good set-piece man. Should be enough to get through the lower league, especially non-league.
