Emmence i totally agree im sure Echo would have major issues if it was as bad as some people say it is bad.
So to all that disagree with the use of leadcore we will have agree to disagree why should i change the way i fish, when i fish this setup very effectively catch alot of carp on it and have never caused any harm to carp.
Andy mate i dont think i mentioned the problems you may have in relation to materials mate, size 6 stiffriggers when using 20-25lb mouthtrap i find it impossiable to do the knotless not and then pass it back through the eye. However if you use a Korda choody size 6 you can do this with no problems at all i use 15lb mouthtrap if im using Esp size 6 stiffriggers,
Anyway Andy you good advice from everyone so take on board what you will and create a setup that catches you fish and somthing you feel 100% confident using... Like i have said it's an awesome rig and get it right it will catch you alot of fish mate.
So good luck and tightlines
