I do rarely catch a whitefish on the perch bibbets but they would probably be caught better using minnows I suspect. The perch bibbets are quite large, round like a minnow, heavy andprobably on a #2 hook or something similar and have no barbs. You let them go right to the bottom then work them within a couple of feet of the bottom. You fish them bare without bait. I heard Dave Genz the famous ice fisherman and inventor of Fish Trap portable shelters was in town doing some seminars. He met some of the guys out on the ice and they said he never knew about perch bibbets before. Must be a Lake Champlain thing. I bet if someone took some to the Great lakes they could clean up on slab perch. The perch slam them and I am not kidding. I buy the blank lures or strip the paint off old ones that don't work and then paint them myself with vinyl paint. The bluegill lures are smaller, light, flatso they flutterand are usually on a 8, 10 or 12 hook and are tipped with maggots.
