Fly lines in saltwater often need to be versatile especially when fishing the Grand Slam Species; Tarpon, Permit, Bonefish, and Snook. Many times anglers will need to cast a variety of fly sizes on the same rod. While these lines don't deliver a Bonefish line as delicately as a true "Bonefish" line, they will get the job done and still turn over streamers, crabs, and larger flies.
