Hey mate cant say im having as much luck as you. Im using little bread fly's the tilapia will rise to the fly get 1cm away from it and just back of, there happy eating the bread all day butt wont even kiss the fly. It is a very visual form of fishing big red beats coming up to the fly. I just struggling to tempt them into tacking it although the local mullet population is keeping me happy. Do you have any photos of the fly pattern you're using the creek i fish is litterd with them and i would love to help get the bugger's out of the water and into my garden.
Thanks Nick
