I fish here regularly, and have had my best results fishing sweetcorn in the margins with my five metre whip. Maggots catch well if you're after roach and perch and the odd skimmer, but corn will catch carp and tench.
I fished here last weekend and caught two carp around 7 or 8lb each, as well as a good tench and a decent sized roach. The bailiff told me that they have matches on the lake every tuesday, with over 20 anglers competing, and he says they are lucky to get three carp between them. I had two in ten minutes!
I think it's because the match anglers use the long pole and ignore the margins. Here are a couple of pictures from my latest visit.
