When they are real deep, I like to tightline them with a 4 jig setup. Gets costly when you get into some structure. That is when I use 1 jig with a 1/4oz buckshot about a foot or so above the jig. I know I probably don't feel some of the bites like that, but it sure helps when you get hung. Just let the slack down and most of the times you can get your jig unhooked. I do the same thing when using shiners/minnows to fish structure that is real deep.
