There is one other advantage to using a metal leader that MT hinted at in an earlier post. I fish for walleyes almost exclusively and any good walleye fisherman knows that means that I am in constant contact with the bottom. That also means that my lures and the first couple feet of line are taking a beating esp when trolling. Having that first foot of titanium leader is some protection from all of the nicks and abrasion. I still have to check and tie often but not quite as much and I know that even if I have just tied when that first good fish makes a dive for the rocks I know I have a foot of durable metal out front protecting the line.
