From the designer, Cheech:

As many of you know by now, I absolutely love tying and fishing sliders. Building them so they swim properly is no small task, and it can sometimes take a while before a streamer passes the vibe check. This one had so much movement that it would try to somersault in the water instead of tracking true. I wanted it to dig down, so I added a keel weight to both hooks to make it move without flipping over. Its extremely easy to cast and pushes a lot of water, and like any of our other tutorials, experiment with multiple colors and sizes until you find what works best in your home waters!
