Those look great. About 40 years ago, I found a commercial version of one of those in my father's tackle box. Caught about 30 or 40 crappie walking up and down a dock dragging it about 5 feet deep. It was solid yellow with a silver blade and had about a 1/32 oz. head. Lost it that same day when about a 2 lb. bass wrapped my 4 lb. test mono around one of the supports.
