I think to take advantage of the movement of any of these jigs, hair or marabou, the water has to have some clarity. I've noticed that they're more popular in northern areas. I've used them both in various waters, and even tidal, but they're not what most folks who fish the same waters will use.
It always made me wonder however, why an angler would fish a marabou jig for Crappies, but not a marabou or hair jig in the same waters for bass.

I saw a show on TV where they talked with some of the guys who fished the Bassmaster tournaments when they first started, and one fellow said that the first time they saw a marabou jig, they thought it was a joke, and wouldn't catch bass. He also said, they found out that wasn't true!

fishballer06, I have a friend who fishes them up there in Erie and does well with them. Also know some fellows who are using them fishing in the 1000 Islands area of NY.
Smaller versions are now popular for the folks chasing Steelhead in rivers & streams that flow into Erie! They use them in western rivers too for Steelhead, and I know of some folks using them for SM bass in rivers that have traditionally been Steelhead and Salmon waters. They're very versatile!

I very much appreciate the comments guys! Thank you!
