Most people think of a craw worm as strictly a jig trailer but when used on a Texas Rig they are quite deadly.

Craw worms are probably the most over looked bait available to an angler yet it more closely resembles natural food than most.

I think this claw thing is a bit overstated.

First, as RW pointed out bass eat crayfish with claws all the time.

Second I doubt that a two pieces of soft plastic floating above a jig are going to be particularly alarming to a hungry bass.

Well, that critter bait has been around for a long time. Gambler Guido bug ring any bells? I personally do not like to use a plastic crawfish with big claws except for spawning fish. For years I used a pocket claw that had a pocket in the claws that you could stick a round rattle in it. It also made the claws float up. Pumpkin green flake with bright orange claws took many big bass for me on beds. On jigs or just flipping I want my claws to float up. I don't use zoom super chunks anymore in cold water because I found that the 3x trailers by strikeking catches more fish for me. I am by no means saying go out and buy 3x trailers but I am saying that the fighting position might draw more attention by a bass then a crawfish acting like business as usual. I know in cold water that little movement when the jig is sitting still and then the claws slowly float up is just the ticket. In my opinion large claws is a turn off to a bass in the way that it might be intimidating to it. I don't feel that the fighting position has as much to do with strike ratio.

when a crayfish acts territorial with its deffencive stance it usually looks more natural to bass
