Has anyone fished this bait? I did order some but I have hard water! They look like the road runner.

I picked up some heavy ones ( 12/ & 3/4 oz) at Cabelas on close out this winter.  I haven't gotten them wet yet.  MY plan with these baits is to either put a big shad body on it (like a Berkley Powerbait Saltwater swim shad) and just swim it back in shallow to medium depths or put a smaller grub on it and jig it deep, like you might fish a Little George.

I think they were invented as a sort of schooling fish lure, but I'm not sure.
