Found these on sale at my local Cabela's this weekend. Picked up 1/16 oz in pink and 1/32 oz in black. Haven't tried the smaller ones out yet, but the pink, when combined with a 2' swirly tailed grub, made for a great weekend of fishing. I've never really fished spinner jigs before, but I am now a believer.
With this single lure, I have caught white bass, bass over 7 #, walleye up to 26 inch, sauger & saugeye, black & white crappie, blue catfish up to 20 #, flathead catfish & channel catfish, sunfish and drum.
