Sean, Changed all mine last fall. Came up with an idea using a fishhook with leader. Take the fish hook and put it through your line. Dont use one too big or too small. use a pair of pliers and sort of crimp the hook down so it doesn't catch on anything. On the other end(Where the loop for the leader is) tie your messenger line. Pulls right through. Untie the messenger line and rehook the new line. Retie the messenger line,clamp down the hook and pull through. When the line is all the way through. Snip of the end of the hook from your line,pull hook out and your done.
