Ultra-light rods. Are rods used to fish for smaller species, they give more sport with larger fish, also enable fishing with lighter line and smaller lures. Ultra-light spinning and casting rods are shorter and lighter, and more flexible than most rods. Tip actions vary from slow to fast, depending upon intended use. These rods usually carry 1 to 6 pound or 4.5 to 27 N test fishing line. Ultra-light rods are capable of casting lures as light as 1/64th of an ounce - typically small spinners, wet flies, crappie jigs, tubes, or bait such as trout worms. Ultra-light rods are produced to bring more excitement to the sport, ultra-light spin fishing is now widely used for trout, bass, bluegill and other types of panfish.
