Tube Flies have been hot items for pike fishing for us over the past year or so, and we've found them to be incredibly versatile and durable. The Fish Mask Pike Tube Fly is a simple tie that lends itself well to variation in size and color, and catches a lot of fish! The Predator XL tubing is the best we've seen for tying pike and musky flies, and the needle holds the tubing incredibly well. You can fit a 4/0 hook directly into the tubing without flaring it, and larger if you give it a slight flare. Tie some up if you're chasing pike or musky on the fly!
