I would probably agree with you regarding the positioning of the bob wires, but the RPRA rules say that they dont have to be, regarding sealing pads why should they be sealed? do you seal your T3 into your shed? fanciers can run all aroud the garden with a T3 strapped to them and nobody complains about that, why dont people just accept when the birds are home they home, ETS dosnt make the birds any faster. If some people had there way we would still be running to the corner shop with the rubber.
