Church stretton/Long mynd green laning

Hi folks, im planning a bit of green laning in the church stretton/long mynd area. Ive done my research on trailwise to the best possible and got my route marked out. But could someone tell me where the more technical/interesting and more serious offroad areas are position please? I have a rough idea of the area, i had a look through a few old threads with fantastic pictures that show a very narrow green lane and another rather muddy/wet one that appears to be on the top somewhere. Could someone please notify me of these areas? Many thanks, Josh
