A grub is a grub, and there is no difference or they are all the same? I can't get behind that. Just like paddle tails, they are all a little or a lot different, and most have a place and time where they work best. I put the Kalin's in with the fat Alberts in the same bag, and it's like a scene from West Side Story, fingers snapping, and switchblades out... "five, six, seven eight"
