Thats a good one AndyG. I dont like using the traditional snell as i dont like the idea of the line going on the outside of the wraps as that seems to be prone to getting cut/chaffed etc and if that happens it weakens it. I use this one here, easy to tie and the line that is normally over the top of the wraps is now protected inside the wraps..
