On the topic of leaders...This year I started to use leader material known as tieable wire. You can find it in the fly fishing section of Cabelas. The nice thing is it comes in a few different Lb. tests and it is really soft and flexible. What I did is tied a 18 inch piece to a few different lures (you can use any knot you like) and then made a good loop at the other end. To switch lures just cut your main line and tie on to another leader/lure. Lures mantain a good action but are protected from toothy gators.
