Far and away, the MOST productive lure I have in my arsenal tackle box is the lead head jig. I can add just about anything I want to sweeten the offering no matter what I am fishing for. I can float it under a clear bobber like the Cast-a-Bubble when I want to trick trout, catch crappie, grab grayling, or even sucker salmon. Ask my son what his favorite is and he will tell you the same. The biggest fish he has taken so far was in the waters off the coast of Juneau, Alaska. (Can you say BIG halibut?) There really isn't a fish I know of in fresh or saltwater that we can't trick in one way or another using the jigs. Walleye and Bass fishermen would almost be lost without them. I know of NOTHING more versatile than the jigs. They come in sizes from the smallest (fractions of an ounce) to jumbo's weighing in in pounds. You can find the heads in every conceivable color, numerous shapes, and hooked to catch anything that swims. You can buy them already rigged with feathers, furs, hair, or synthetic tails, etc. or you can rig them yourself with any number of live or dead natural baits. If I have but ONE choice for my survival pack, it WILL BE jigs! Need I say more? ;o)
