Being the inherent tight wad that I am, I only put about 10yrds at a time on my reel with a full reel of mono spooled up. This is for vertical fishing. Unless I brake off "up the line" it will last a long time.
Side note_ I use HI VIS Yellow Sonic braid which I can't find any more but bought a bunch when I heard it was being discontinued. I liked the suppleness of the Sonic over the Power Pro.
