I've been doing some research and I think i've narrowed down the difference between a leader and a shock leader: "A shock leader is a leader long enough so that half a dozen wraps of leader remain on the spool up to the moment you release the cast. The knot that joins the leader to the running line comes off the reel and goes through the guides during the cast. If that knot isn't on the spool and under a few wraps of line when you release the cast, it isn't a shock leader. If the running line's connected to the leader by a knot or barrel swivel that stays outside the tip, it's a leader, but not a shock leader." So now that I know the difference between the two I have a couple of questions: 1) Are Shock Leaders and Regular Leaders commonly used together? 2) If using a shock leader w/ a Carolina Rig what am I attaching my sinker and bead to? If it's a barrel swivel, are you attaching a different piece of leader material on the other end? I guess i'm confused because alot of folks on here seem to be happy when a leader side of a knot breaks on line-to-line, but if this is the case wouldn't you also lose your sinker, bead, swivel and hook too? Example Carolina Rig: reel------------------braid-----=----mono shock leader------sinker/bead=barrel swivel=----mono leader-------=hook ~~~~~rod~~~~~~~~~~~~~~~~~~~~~~~~ = - knot The above diagram sort of shows what i'm trying to explain in a Carolina Rig w/ Braid as your running line and a mono shock leader. If your line-to-line knot that connects your braid to your mono breaks you will STILL lose your entire shock leader along w/ your sinker, bead, swivel and hook. What am I missing or doing wrong here?
