You can get away with heavy monofilament or fluorocarbon for smaller toothy fish, such as Spanish macks and little blues (not ‘cudas!) but if the macks are “max” or you’re on some kingfish, wire is a must. When a sizeable toothy fish clenches its teeth, your fly is gone. Now I make it habit to carry both singlestrand and braided wire leader, and there are new products that make it easier to rig up for flies.
Here’s a cool little short for fly guys, not to mention, if you haven’t stalked the flats in the Florida Keys yet, this might just convince you. Join captains Bou Bosso and Brian Gabriel for an up close experience of a great day on the water sight fishing for redfish and tarpon.
