adamu, I use them also--from 3/8 to 1 oz but only on 50 and 30# lines...although I did catch a swordy with 3/8 oz on 80#...go figure.......above posts are correct, especially use above swivel....I also use eggs on everything....banks/rubber bands good idea...if you watched "Wicked Tuna", you'd have noticed they used bank/rubber band setups for the giants...
Sometimes I'll slide the rubber core up the line10-30'...that seems to work, also...at least for me
