35-lb.-test Gel-Spun Backing gives you more capacity than using 20-lb. Dacron®, which is why it is the backing of choice for big-game angling. Braided from gel-spun polyethylene, this incredible backing is 10 times stronger than steel in equal diameters. A very small diameter for higher yardage on the reel means slower spool rpms on runs and faster pickups. Gel-Spun has virtually no stretch, is extremely abrasion resistant, yet has a very low coefficient of friction so it will not damage your guides, and retains 100% of its strength while in the water. Unaffected by UV, gas, oil, salt, or detergents. Chartruese comes in 30 and 45 lb.
