I just bought some of the ringer stingers from BPS. Looks alot like those. Haven't had a chance to use them yet. The little straight tail puts off a lot of very undulating action. If you hold the head between your fingers, you can't hardly keep the tail still. I'm dying to try them on a very slow vertical retrieve or just sitting still. Any bumb in the line wil activate this tail. Maybe someone can fill us in who has actually fished these and how.
