The Hack Attack "Fluoro" Flipping Jig is a compact jig designed around a strong black nickel hook that has a smaller diameter (than the "Heavy Hook" model) to get good penetration when using fluorocarbon or lines that stretch more than braid. It's head shape, weedguard and size make it extremely weedless and its cork screw wire keeper secure your plastic trailer. This is the best flipping jig there is for heavy cover when you want to downsize your line such as in clearer water conditions.
