Well the one on the right looks like hackle. I started with feathers and switched to synthetic craft fur/hair. It is much cheaper than feathers and I like the motion of the hair better than feathers while the jig is still in the water.

Hobby Lobby has some good stuff to use and there is a place in California...Western something that sells a bunch of different colors of the craft hair. $2 to $3 of the stuff makes a couple hundred jigs at 1/16 oz.
