Fair play, I would rather be outside the city myself. I've fished that bend were the banks steep down to the water a few times and had some good catches with a few well over 100lbs. Mind they have always been summer and autumn so not sure if the bream hole up there in the winter.
The way I always fish the yare when after bream is keep it simple. I kick of with 2 kilos of groundbait balled in which is, senses bream and brown crumb,small amount of fishmeal and then caster and small corn. Rigs are straight forward running rigs with open end feeders, start with a 16 hook to 2 1/2 hooklink and step it up if the fish are really having it, then it can be 4lb links to 12 hooks. If slow drop to 18 hooks.
Hook bait is double caster, redworm or bunches of maggots. In that swim I fish about 1/2 way across to avoid the dead lillies closer in and to hit the deeper channel. being winter I would drop down on the amount of groundbait, maybe just focus on going in on the feeder, recasting every 15mins if I haven't had a bite. The inportant thing is if there is colour in the river, if its really clear it will be hard work, if you could do after dark it might help.
I know bramerton does some big bream in the winter and lots of them especially after dark.
