I just had a random idea about this and I was wondering if anyone had ever used any of that powerpro fishing line for backing. I assume that most people have seen it or used it. It is basically a braided fishing line that is supposed to have the same test strength as normal line, but smaller in diameter. I figured it would be a pretty good idea to use this on fly rods since backing can take up a lot of room on smaller reels, and you can always use more room for actual fly line! lol. Kind of a long post, but simple question. Sorry. Summing it up: Could a guy use powerpro braided fishing line for backing?
