This nylon is chosen to neatly spool a big-game reel with a reliable, consistent line that is strong enough to withstand long fights. The transparent color remains inconspicuous in the water and is suitable for setups where the line should not be too visually noticeable. The available strength classes cover the heavy-duty ranges used for tuna and other large marine fish. The diameter should be chosen based on the reel’s capacity, the drag system used, and the desired level of abrasion resistance. The 1000m spool allows you to fill several reels or restock your line supply without having to work with a spool that’s too short.
