The Bull Brim is a unique 5′ long 1.5 ounce glider in that it is in the shape of a bluegill, not a trout.. But it has the same S-curving action when retrieved through the water. It is a deadly bait on giant largemouth bass, muskies, pike, and saltwater species. Just cast the Bull Brim and retrieve slowly. The bait will walk back and forth in an S pattern driving the big one crazy.
