Thanks for posting. The version with only the "pork frog" on a ball head jig looks a bit like the Strike King "Pad Hopper". I had bought a half dozen of these and carried them in the boat for years. One day, fishing a new lake, I just couldn't get bit -- found them in a box and tied one on. On that day, they worked magic.
Unfortunately I couldn't find any more of them. I wound up trying to sculpt my own out of some other miscellaneous plastic lures and came somewhat close. Anyway I think the action of their legs flapping on the fall was what flipped the switch that day. Hadn't thought of trying to make my own using the basic pork frog profile as the starting point. Have never poured my own plastics, but I will give that a try when I get back home for the summer.
Thanks again.
