Hi mate been fishing it quite a bit and had varied results but I think more due the weather an water temp than anything. There is a lot of weed at minute and the fish seen to be either out really far or tucked under and in the weed. Had plenty of success with simple nymphs (hare ear, diawl bach) around the weeds and literally dropping it into the holes in the weed.
Also have had good results on the dries with fish to 5lb taking griffiths gnats and hoppers. Just remember to cast short and work way out or simply target them by sight fishing.
Bit fed up of going and hearing people bad mouthing it "no bl**dy fish" etc. there'splenty and you just need to work at them. Had 16 out 10 days ago including 3 browns.
Hope it helps.
