Ok, figured I would throw this out again. I do not do this for a business but to help fellow fishermen out. I make my own lead wire (.185, .205, .250 diameters). This is solid core continous wire that I extrude. What I have done for some in the past is to make the lead wire for a split of the lead. (must be pure lead). If you have the lead I may be able to help you out. Just thought I would offer.
