Tuna Sticks are available in Anodized Aluminum and in a heavier Electropolished Stainless Steel. Tuna Sticks screw into the back of any of MP Lures' screw head models but are most effective when used with Aluminum or Chrome Brass Bullet Heads. The SS ones can also be used to increase the weight of Medium and Large MP Lures used in conjunction with Plastic skirts. The small tuna stick will screw into the inside back of a medium skirt and likewise a medium tuna stick will screw into a large skirt which is popular when high speed trolling for Wahoo. Tuna Sticks are made in a straight tail for a fast wiggling action or a flared tail for more of a swimming action. Both styles have a large enough hole for a conventional ringed eye hook ( don't need a needle eye).
