I will never use Vanish again either, even though the Vanish hitting the shelves now say NEW and the rep said they admit there were some quality control issues. My experience with it spoiled it for me forever.

I'm curious as to why you would even bother fishing flourocarbon when you're already using 8lb test. The line will still show some amount of flash just not as much. 8lb should look about like 5. You get the real advantage when your fishing something like 17lb which shows like 10. Imagine being able to pull logs out of log jams and the fish only seeing your line like it's 10lb test Now that's what I'm talkin about!
