Sufix is great. But it losses color faster than Power Pro and Stren Sonic Braid. All turn mostly white after a couple days of casting, so it is unpreventable. Out of the three lines I listed I would rank them: Sufix, Stren, Power Pro. I have not used Tuff Line. I use 65, 80, and 100 lb test when using actual musky lures. I go to 50 lb when downsizing to smaller, bass style lures in the spring.
