I filled my reel up with the vanish floro line fished with it for three days last year on the opener. When I got home it vanished off my reel to the dump. I lost way to many fish. I didnt like the way it felt when a fish was biting. I troll most of the time and the fish would hit it. It felt like the line was solid no stretch nothing. So one good dink on the line and fish gone. I switched back to izorline and its mutch better stuff no florocarbon for me. I have heard that the more expensive stuff like seaguar is better but I aint wasting anymore money to find out.
