ive got two hobs and two gills which a seperated every ones each to there own i have only every used hemp nets which are hand made by myself or my dad if there are looked after hung after after use to dry out they dont rot and can last for ever ive probably got 100-150 in use at the moment. however if money is an issue then buy nylon try and use the heavier plys as the dont tangle so easy. As food goes dry food can suppliment a diet now and again but try and not chop and change there diet i feed mine shot woodies one a nite with the occasionaly half a rabbit between two each nite.
