Stren's new High-Impact fluorocarbon leader material is just the ticket for fooling sharp-eyed species such as bonefish and tuna. Not only is High-Impact less visible to fish, it's also waterproof, impervious to UV rays and highly abrasion resistant, making it ideal for fishing around roots, rocks and reefs. High-Impact is available in 25 yrd. wheels in 10 through 80 lb. test, and in 33 yrd. coils in 10 though 400 lb. test. Stren, Madison, NC; (800) 243-9700; www.stren.com.
