Tie the Airflo FIO Tips 10 Fly Line to your setup, and start your hunt for a steelhead. The sinking tip is specially designed to drop your fly to their level quickly, while a bit of intermediate line creates a smooth, unobtrusive transition to the rest of your line. The Power Core ensures timely energy transfer when you go to set the hook, and its Hi Density Polyurethane coating sheds water and grime to maintain durability.
