Hi-Seas’ new Grand Slam Fluorocarbon Bluewater Leader comes in an exclusive blue color crafted with a proprietary process so the leader “disappears” in offshore waters by matching the light refractivity of salt water. The new leader sinks faster than mono and remains soft yet abrasion resistant. The fluoro comes in 25-yard bags of 40- to 175-pound-test. Bags cost $18.49 to $61.49.
