The way ledgering,in particular for barbel has developed,it is crude to the extreme,following the carp lead,anglers using 2-4oz leads when you could hold bottom with far less,with their backleads(another bloody 1.5oz of weight on your rig),or even worse leadcore,without which creates the bowstring effect,which in turn scares the hell out of the barbel,i blame the pathetic 'how to do it' articles in the mags,whatever happened to learning to fish and getting bits of advice and expanding your own methods,we used to fish with just the minimum weight to hold,pull some line of the spool,so as when a barbel swam into the line the resistance wasnt so frightening experience(similar to weed passing over them perhaps),i know of rivers where fish will hole up if more than a couple of casts are made with a lead(or even a heavy bait),making trotting for big barbel THE method.
Mark,i know you dont use these heavy leads unless they are required,so your angling experiences over the years,buck current tackle trends,so you become that dinosaur,lol.
