We've been using pike tube flies a lot over the past year, and have found them to be incredibly versatile and effective! The Hog Farmer is a simple tube that has caught a lot of pike for us, and it's a fairly simple tie that can be tied in any combination of colors/sizes. A 4/0 hook will fit directly into the Predator XL Tubing without flaring or junction tubing. If you're chasing pike or musky on a fly, you should definitely have a few of these in your box!
