I think that the Rebel Wee Crayfish series is one of the 'all-time' great lures for ul and stream fishing for a variety of species. I have taken smallies, largemouths, sunfish, rock bass, carp, cats, crappies and other game on these great little lures.
The smaller profile minnow and crickhopper plugs are ideal for rigging with 'tail-gunner' set-up on shallow or bedding bluegills as pointed out in my blog on this site.
The tiny Wee R Crayfish catches several different panfish in my home lake...White and Yellow Perch,Bluegill,Sunfish and Crappie..The Rebel Wee R is THE favorite Trout Lure when Trolling...Don't quite know why but it out produces(Trout catches) the Bomber 4f and 5f Cranks that I catch a lot of species with also .
