Boron is five times as strong and twice as stiff as steel, yet lighter than aluminum. It adds 25% more strength to graphite while significantly reducing weight. Boron IIx rods take full advantage of this material's amazing properties and have redefined the fast-action category. They are responsive, powerful, highly accurate fly rods with a very wide casting range. Whether it's gentle presentations up close or long casts of 100 feet, a Boron IIx can do it all. Incredibly light, these rods are a pleasure to cast all day, even the 10- and 12- weights. In excellent condition with original od sock and aluminum rod tube. No warranty.
