Hey Woody,
Revheads are made by TT lures and are good stuff but for bass I use ponyheads that have a brass willow blade that swings a bit looser than the revs. Secret Creek lures have been making them to my specs for a while now so they are the same as the ones I make and used in Wild River Bass DVD.
I can tell you the bass love them with a 2" soft plastic grub on the hook.

P.S. 1/8oz are the best weight for rivers.
