I was thinking of getting a barbel rod made up many years ago,I wanted it shocking pink,just to prove what load of rubbish is talked about matt varnish,dark whipping etc,it makes no difference....unless you are wearing a bright shirt whilst bobbing and weaving,a bit like swivels,people try to cover them because any glint will spook the fish,well I've had big fish of all species feeding next to diet coke cans and the like,in very clear water,they were taking bait next to them...
