Berkley has a Gulp Ice Minnow Head and Northland makes an Impulse Minnow Head. I still like natural and believe that salt always helps so I save all my dead or unused minnows, salt 'em heavy and pop 'em in the freezer. If they're salted enough they don't freeze real hard so they're always ready for a trip. After all, you're gonna rip their heads off anyway. Very handy, effective and value minded.
