I change it out once a year, and try to stick with Suffix for most of my mono needs, but use Yo-Zuri Hybrid for my heavier jig and spinnerbait rods. I only use Power Pro braid, I have used it to long and know how good it is. Depending on what I am doing, I normall change lines twice a year, but have to respool with braid sometimes up to 4 times a year after clients get plenty of birds nests on the spinning reels. I used to change line out before every bass tournament, and still do the same for King Tournaments now.
