This is what I do. I tie a #2 "snap hook" (JannsNetcraft.com) to my leader using a palomar knot and leaving a long tag end. Then I tie another snap hook to the end of that tag using a Trilene knot. This allows me to quickly switch/change my jigs without re-tying - and it give a free loop knot type movement to each jig. Has proven itself over many years of use.
