Foam materials such as polycelon slices, cylinders and variously shaped and colored heads are modern tying materials that are used in all branches of fly tying. They find use in tying modern hoppers, cicadas, beetles, but also large poppers, guglers and floating immitations of dead fish fry used for fishing of predatory fish and large trout.
Polycelon cylinders are great for tying Booby Eyes of Booby Nymph patterns. For this purpose are perfect Floozy Eyes, which have already been shaped and you don't have to modify and trim! And so if you like to fish with your own Booby Nymph, definitely try this material!
