I usually use a snap on my top water plugs such as a spook or a chug bug. Never had one to fail me yet, and Is alot quicker in changing out your plugs and still get the action you want. Here Is a web site similiar to what Msgmills was referring to, or maybe the same one that shows alot of knots and how to tie them. The loop knot Is not listed as such, however I think It Is listed as a rapala knot Instead. Pretty neat...check It out.
