Pro Predator cones are designed to specifically fit Pro Predator (Classic XL) tubing within the Pro Sportfisher system.
Predator Cones are large diameter to create a hydro-static void forcing material movement on big Saltwater, Pike, Musky and Bass Flies. They are not ultra heavy as sinking big flies is not generally the main objective as much as breaking the surface tension and leveling out big flies. For ultimate durability in tube fly systems try lining Pro Sportfisher Predator tubing w/ Pro Sportfisher Classic Large tubing. Pro Predator cones feature perfect fit and finish that Pro Sportfisher is known for in the realm of tube flies. 7 cones/pack.
