Boron III LS perfectly blends the incredible "Winston Feel" with Boron III technology to produce a modern light line series. This medium-fast action series is lively and responsive, and delicately presents a fly with extraordinary accuracy. Built with advanced Boron III technology, this remarkably lightweight series has incredible touch, feel and control. These rods are the ideal selection for small stream enthusiasts, anglers using light tippets for big fish, or those who enjoy stalking big fish with small flies. The Boron III LS sets a new standard in what one should expect from a light line series. However, with eighty-plus years of company history behind the development of this series, it really should be no surprise.
