Re: A bleak day fishing
You could try minimising your locking shot and bulking your shot about two thirds down then one small dropper shot about 6 inches from the hook, this should get your hook and bait down quicker and get past the bleak.
Or try a bigger hook and bait, a size 8 or 6 with half a lobworm on that's too big for the bleak and will attract your perch.
Or try stret pegging
