The Game Changer shank design was and is the staple in multi-articulated joints, or as what I like to call vertebrae. When I was trying to make a fly swim like a real fish, I tried many ways to achieve this serpentine swimming action but failed many times. Until I sat back and thought about what makes a fish truly swim? There are a couple of key things, muscle, fins and most importantly, their vertebrae. I used a wire bender and stainless-steel wire to play around with different lengths to achieve the desired swimming action in relation to the size of the bait/fly. The results became Game Changing for me, my fly designs and fishing. With these shank designs the Game Changer fly was born and giant fish haven&&';;t been safe since. Use these shanks for all types of articulated flies and enjoy the results on the water. I guarantee they will "Change Your Game"! Key features to these shanks are a closed eye reducing the chance of the eye opening up resulting in loosing fish. Also, the correct wire gauge and loop openings keep the platform strong and light with the most amount of swing/swim. And finally, having the returns on the wire shanks come all the way to each end to allow for a clean and even tying platform.
