bugtussle, the threadneck version is very old school and was called a pinky jig back in the day, today a guy has to make his own or have them custom made. the hair gets a lot softer once it gets saturated with water, and also they tend to catch more fish by staying a little sparse with the hair, this lets the hair move a little more. I know of a few local crappie fishermen who are top notch and kinda secretive in what they use for a jig, and I can tell you that they hold the kiptail jig in very high regards. they tend to use the 1/16 sizes tipped with a small minnow for spider rigging and also jig and bobber methods. there is a guy on our Virginia forum this last few days by the name of Vacrappieman and you might want to check out a couple of his pics in those posts. we use the smaller sizes a lot in ponds to, 1/32 etc. and tip them with a crappie nibble, just fish it like it's a minnow, I just let it sit, and my buddy is always jiggling his bobber, and he usually catches more than I do too. so I give him some jigs and he wears me out with them, he's been using them for 50 years.
