I have a couple of Church's mini planers. They's Bout the same thing. Mine sunk with a 1/4 oz jig. Mine also dive like a dumpster digger. Billbob brought me some thin styrofoam sheets and I glued some styrofoam to fit the planer back. They don't sink now and I have caught fish using them. They are a PIA for an old man though. I only use the planers when fishing slows down in the summertime.
