Included in the Plus series are three extra powerful, reinforced Jungle rods designed specifically for Peacock bass and Dorado. The Plus series also includes high-performance freshwater 5wt. and 6wt. rod models. The “Plus” stands for incredible line speed, extra power and design qualities needed to handle monster flies, the wind, sinking and oversized head lines and of course, big, big, fish. Boron III Plus rods are lightweight, smooth casting and feature our new shooting guides, green reel seats and, of course, unmatched Winston quality and craftsmanship.
