I agree, it tends to be a bit hipocritical when fishos are all for our waterways and the environment and yet they use these forms of fishing which kill parts of the eco system, although indirectly..
What about small foam floats, i think one could be attached via a floating line using 1 swivel on each end connected to the leader below the swivel.. somehow it could be clipped in place or something or even made so it could be a full floating set up??? and be reusable? I am sure i could make a prototype and take some photos to post... actually i will have a crack tonight
