I like kipp tail a lot. The original Doll Fly Jig back in the day was made with polar bear. Kipp tail is the closest thing to it. Has great action. Stiffer than fox tail and softer than buck tail. Has a simular texture to Polar bear. Kind of kinky. Kipp tail with longer hair is harder to find so its better to see it in person to make sure if you are just tying 1/8" jigs. I have a lot so I just match to the size I am tying. If i could only tie with one material....that would be it.
