UPDATE 7/19/09
These things work !! Went out last night to a sand quarry that is known for huge fish. My buddy had fished it his whole life and said it's the kind of place that you get skunked a lot, but when you do hook up it's worth it.
Had one of these rigged on a 1/8oz tube jig. Felt a subtle hit, set the hook and away she went. Had her going good. Then she jumped, did the head shake and she was gone :'( She was a beast, easily 7-8 lbs. Other boats were around, everyone saw it. Oh well, I'll be back.
So I guess I answered my own question about these baits.
