Copper May be a little easier to attach, but definitely not easier to run. Weighted Steel is by far the most fisherman friendly weighted line available. Used the shrink tubing method and ran 200', every trip and 300 almost every trip. Never one problem. Including a huge tangle with a leadcore that would have ruined any copper. Layed out on my boat floor and untangled it all without one kink. Will be adding couple shorter steels 100, 50' for sure. Sent from my XT1254 using Lake Ontario United mobile app
