It's not an everyday strategy, but bulking up the bait's backside occasionally bears benefit. Consider these points:
• Profile — Big fish prefer one big meal over chasing hundreds of tiny nibblets, so a larger spinnerbait profile can get you those game-changing bites.
• Displacement — In dim, murky or otherwise low visibility, a big tail pushes more water and gives fish more of a target to locate.
• Motion — Swimbaits, ribbontail worms, full size Brush Hogs or any oversized trailers with specific tail movement add even more life to a spinnerbait.
• Color — Trailers offer a quick route to color enhancement, and when you really need to get noticed, the ability to dress up your spinnerbait's visage can prove invaluable — especially in dirty water. Dip that big trailer's tail in chartreuse dye and you'll add another level of attraction.
• Rate of fall —Bear in mind that larger trailers affect fall rates. That can work for you or against you, depending on what you're trying to accomplish. Also, the drag of a larger trailer limits your ability to burn a spinnerbait.
