well im a horrible flasher fly dodger squid fishermen and take tops of 5 fish a year on them and i keep buying them? But i dont run them on lead core i think theres two much twisting in the line and if you do run on lead them buy the best ball barring swivle you can buy there worth it or you can have a good mess of leadcore. i run them i maily run them on riggers and low and high divers, iv also had some good luck with baby spin docs and small spoons it was a great offshore set up.
