I'm with Odie and the guys who support cheaper rods, braided line, and proper drag setting. If you don't have some already, get the Depth Hunter Power Pro. It is a braid with color coded marks that give you absolute depth control, without tying on strings or using magic markers. It is available on eBay at several sites. I use a small swivel tied to the braid with a Palomar knot, and add one or two 4 pound mono leaders. Otherwise I would be shortening my braid every time I put on a new jig.
Alternatively, you COULD tie loops in the braid and change jigs without cutting any braid. And the braid will straighten or break any jig hook you use if it gets hung in the brush or other lines.
