i know its a little out of your club waters but i fished the southsea blocks today on a charter and had 3 plaice, i think most people apart from a couple on board had 1 or 2, not bad considering the weather, it was freezing and the hail stung your ears! the water was quite cloudy too which didn't help but the small delta sonar spoon green/black beads seemed to work cos no one else got 3!
i also noted those using multi bait traces had more success, maybe due to increased scent
