BV Cub Spinner Blades are contoured something like the bowl of an actual desert spoon. Their rotation is dependable at nearly any trolling speed. BV Cub blades are more pear-shaped than Colorados so they have less drag. This makes them a great choice for use in trolling behind a 360º Flasher. Size 1 is nearly identical in length to a 3.5 Colorado. Size 1/0 is a little smaller.
