I ave used Vanish, Transition, P-Line Floru, Seaguar Invizx and Berkley Trilene Fluorocarbon. I had nothing but problems with Vanish and Transition The Seaquar and Trilene Floro are great don't think you could go wrong with either. I have started using the Trilene more often because it comes in green, not just clear, and I prefer green.
