Also called J plugs CMS has them and they are very good for stripers caught a few this past weekend on a herring colored one. Great for trolling as they do not tend to pick up weeds as fast as other lures. I troll then on 45# leadcore line that way you don't need to pay out lots of line to get them down. The next time you are out trolling give them a try you may get (hooked) on them your self.
PS that was in Fairhaven waters to boot!
