Stay away from Vanish. Try Seagar. I use 15 lb. Seagar on Lake Ontario and it is the only thing that will hold up to 30+ lb. king salmon. Seagar is more abrasion resistant that Vanish or Stren. I have tried Vanish, P-line, Ande, and Stren florocarbon and Seagar is the best by far. Seagar is a little more expensive but well worth the money. The have it in the Cabela's saltwater catalog. Last season I iced many large pike 36" - 41" without any break offs.
