Tapered leaders are the ones I use, they are very long so you have plenty of leader line to hand-ball a fish up the pier side, but the main advantage is you can tie the neatest knot possible because you can trim the 'fine' end of the leader to the same size as your main line. So instead of a bulky knot from your thin main line to a heavy leader line, you end up with a knot of equal thickness. They aren't cheap though, but I think you get about five on a spool. Fraser's Angling at Whitley Bay stock them, and they will keep you right about how to tie them. Personaly I wouldn't use anything else now, especialy as most of my fishing is done over clean ground and beaches.
I use them on Blyth pier and have never had any problems. It certainly helps when your lifting a fish as you are pulling on heavy diameter line which is not only strong it is much kinder on your hands. Having said that, you aren't guaenteed landing a fish, as I lost a cod about 5lbs on Monday afternoon whilst fishing the pier. The line didn't snap, but it wasn't well hooked and the hook tore out.
