if you want to drift with bare chunks of lead, why not just crimp split shot flat onto the dropper line??? it would make it a whole lot easier than threading little sections of hollow core and quicker to add/delete weight as the conditions change throughout the day. another plus is that the shot is round and not square like the sections of pencil lead when they are flattened.

hey, better yet, why not just take that shot and slip it into some parachute cord?? then it would really slither over those rocks and rarely hang-up...oh, wait a sec...thats already been done, nevermind
