I have a custom mold that I had made to pour this size head for two different flies I tie, a regular crappie feathered jig and my Chet Flys. But it only pours the head itself with no colllar. I always wanted one with a barb for holding plastics better and I think I know where I can get one...lol. I always look for a reason to do a little custom work anyways...lol. THANKS Kelly
