Anyone ever tried this and had success? I was thinking of trying it due to my waters being very muddy lately, thought it might give out a bit more thump. 

Why not I’d try it. I bet you’ll catch something 

Yes

I haven't tried it, but bet it works.

When they first came out they were popular as a pitching bait because of the bulk and thump. I'm sure they'd work on the back of a jig too, just like a bulky speed craw.
