I saw Dave Lane fishing zig rigs with dog biscuits on Suffolk Water Park in swim 1. The swim is at the extreme left of the far arm, and he was casting to the left side of the swim, next to the rushes, and continually firing in mixers. The little wind and drift there was was pushing the floaters to the left towards the rushes.
He had a number of takes from there, including the biggest fish in the lake close to 40lb.
