Lead bag, Terry Eustace used to do a padded odds and sods bag (had mine 10 years plus and still good)
Quiver, Both the wife and me use Trakker 5 rod quiver and sleeves bought separately when money allowed.
Bank sticks, Stainless I`m afraid (heavy but as tough as cockroaches) but pricey
Bobbins, Cant fault Gardner bug cradles for slack line work and I still have my blue osprey light up bobbins (tarty but I love em)
Landing net, Mesh loose from Tackle box, Handle Daiwa Black widow (tough and light) Arms and spreader cannibalise your existing.
Well that's my 10 pence worth I`ll get me coat
Cheers
Ian
