Like smaller Ugly Bugs these larger and heavier models walk rock bottom virtually snag-free. However, these larger models do it in water depths from 30-100 feet deep. The new heavier Ugly Bugs are ideal for working deepwater bass, stripers, walleye, lake trout and salmon species. When vertically jigged, these heavy jigs always hold a horizontal position enabling the fish better strike engagement. In fast rivers, these new heavy Ugly Bugs work great below dams and deep channels. Buy white, yellow, orange and chartreuse for lake trout, salmon and stripers. Buy the darker colors for bass. Use both light and dark colors for walleye.
