I've lost countless jigheads while fishing for flounder over rocks and oyster beds. To try to cut down on the hang-ups, I got a bag of 3/8-inch rubber bands (the kind that people use on their orthodontic braces) and stretch them from the barb of the hook to the eye of the jighead. While it doesn't completely solve the problem, I think it has reduced the number of snags. The rubber band pops off easily when I get a strike, so I don't think it affects my hookups. It also works great in the weeds.
