Can't say to that. In my area Tuffies were the only choice to be had. Sometimes you would get a Rosie in there. But it was purely by luck because they didn't have any for sale. They would devour the Rosie. I think that it was more along the lines of it being different than something they really prefered. When night fishing using lights. When they were feeding on small shad circling the light. They would hmer a caught shad over minnows
