Hi Robert, very small feeder (tape to allow maggots to trickle out), block with groundbait, 12" hooklength 1 1/2lb BS to size 18-20 hook, DO NOT fish any heavier or you'll not get bites, cast to middle of canal, expect roach/perch to 4oz, and occasionally, bream to 5lb, chub to 2lb, no groundbaiting or loose feeding necessary.
Apologies for being late with info.
