I've got a couple lead filled copper pipe jigs...each has 2 treble hooks offset from each other protruding from the body. I've read that they're very effective on lings and halibut....but then so is just about anything if you bonk them on the nose with it. I'm wondering if copper is particularly significant or if any old chunk of pipe would do? A chunk of galvanized pipe is a lot cheaper than copper and could eliminate the need fiddle with melting lead. I never have seen one in a store. Anybody out there use 'em?
