Vanish works great if you know how to use it. Firstly, any time you would want to tie a clinch knot, you need to tie the improved clinch knot. The normal one will not hold. also, you need to make sure the knot is very wet when you pull it tight. Also, pull it tight slowly. I personally use 14 lb Vanish on a regular basis and have never lost a fish to it. I've even landed 17 lb chums in heavy current using it.
