Tied with kip tail, pinkies are a favored style of jig for my mid-winter to early spring fishing. I've caught trout, bluegill, crappie, and both largemouth and smallmouth bass with them.
Each is tied on a 1/32-ounce darter-head jig possessing a #6-8 Aberdeen hook. Used a 70 denier (or slightly smaller) polyester thread to keep the bulk down on the jig collars.
I like to tip these jigs with curly-tailed grubs of about 1 inch in length and fish them beneath a float. It's a bit like still fishing, but during winter it allows you to take in your surroundings and enjoy nature's wonders. Do dress appropriately to stay warm!
