The Hanak Fluo UV+ tungsten bead directly correlates diameter and weight, and comes in red. The red color complements black, brown, or copper-colored nymphs, adding a warm accent. The fluorescent finish reacts to UV light and clearly highlights the head. Sizes range from 2.00 to 6.40 mm and from 0.06 to 2.00 g; packaging: 20, 10, 7, and 5 pieces per bag, depending on the diameter. First, choose the weight appropriate for the depth and current speed, then make sure the diameter fits the hook you’ve selected.
