Just a thought that nobody mentioned... Is the tip of the line sealed. If not water can wick up the core & destroy the hi floating qualities of the line.
I heard that a good cleaner/ floatant is Alboline makeup remover. I know it is a dynamite fly floatant & I have used it on my furled leaders to float them, but I'm kind of leery about using it on $50.00 line. Has anyone tried it????
