I cut my teeth trolling Hal Flys in the 70s. My fishing buddy's Secretary was Hal Barber's daughter in law, so he got all kinds of inside scoop on fishing methods. Our go to jig then was the 1/32 red,silver,white. This was a Malibu tail and it killed the crappie. Stumphunter jigs, tied by Ronnie on the SC website, has a dead ringer for the old Hal Fly that we used. I just got a dozen from him. Just search for Stumphunter jigs.
Note that the old ones like we used had a silver thread body, not the jell type that came later.
