Personally, I would not call it a Popsicle. George Cook developed and popularized a series of "Marabou Flies" and gave each a name. The Popsicle has three colors of marabou palmered up the shank of the hook, orange, pink, with a purple collar. A variation of Cook's Popsicle would have to follow the same color pattern, with the variance being in the material. Marabou flies (a fly with parlmered marabou) can be tied in any color and in any color combination. My favorite for winter steelhead is a tri-color in yellow, pink, and orange, which I caught my first Skagit Steelhead on. Dec's go-to guide flies back in the day were Marabous, for good reason. I would as well not call your fly a forgery. It is a fine-looking Marabou with a twist. Far too often flies get lumped into the namesake of a popular fly. The Popsicle is a perfect example. A fly tied with multiple colors of marabou does not make it a Popsicle, nor doe it make it a variation of a Popsicle. It is true however coming up with an original Marabou Fly would be a stretch. Adding flash, underbodies of synthetic material, craft fur tails, and such to improve a known fly is a common theme and no one should ever impede someone's creativity at the vise. Giving credit where it is due is important, knowing where to give credit comes with an effort to learn. Keep up the fine work and I would fish you un-named fly with confidence. If it works give it a name.
