Serious fishermen who spend a lot of time on the water will truly appreciate the Mepps Double Blade Aglia. It's perfect for smallmouth and largemouth bass, trophy northern pike and early-season musky. Why two blades? Dual blades create additional flash. This, in turn increases the intensity of the blade colors as they spin, whether the blades are the same color or contrasting colors. In addition, the sound and vibration they make is noticeably different than a spinner with a single blade. Two blades also produce more loft so they are easier to fish over weeds and other structure.
