...pike streamer?

The hairs are short, but you can make a pike streamer from it. You can cut the patches in narrow strips like zonkers. This alone would be too weak to tie in. They will break easily. To counter this you can rub the strips with silicone kit, rubber repair glue or Loon soft head. Allow it to dry and then you have a fantastic pike streamer in your favorite colors. While tying you can add some flash.
