I can get these for a pretty good deal, but sometimes you get what you pay for.

Anyone have any experience with both the 4" and 6" versions?

A very odd looking bait.  I would try it out, I have had great success with Gambler baits.

Val from gambler lures sent me some to try before these baits hit stores last year.  I have to say that the 4" baits are a deadly finesse bait.  They sit great on standup shaky heads and the tail just quivers.  I loved them for smallies and clearwater situations.
