RJ Boyle makes the best wind-on leaders in the business. Our swordfish wind-on leaders for daytime fishing come with a wax loop at the top to hang your lead on. We use a specialized waxed dacron and have a double wall over the top of the mono inside. We insert our mono roughly 8-12 feet. Daytime swordfish wind-on leaders are made with 250lb mono. Offered in two sizes: 100ft for slow current (1-2 knots), 150ft for stronger current (3 knots and up).
