Have read with interest the threads on line --on hooks -- reels etc. Now to that last piece the connection from leader to main line. Question is what type of knot is best used with 12lb test when tying to a swivel and what type of swivel is recommended. This seams to be the week link I can sharpen hooks, replace leaders, replace beat-up line however I always have doubt about the connection I have made. Any recommendations?? Thanks
