There's nothing wrong with Fury. I you're interested in it give it a try. If you don't like the material you can always sell it to someone that likes it. I build a lot of strings and there's no "one perfect material" for all of them. I mainly use BCY and prefer 8125G. It's just what I like. I've put strings on bows that don't like anything other than B50 or B55. I've also seen ones that really seemed to prefer a skinny fast flight set up. It really comes down to what the bow and shooter prefers. If you start building strings you're going to experiment a bunch. It's just going to be that way. Curiosity will get you every time! That's just part of our sport. We're always looking for different ways to put an arrow down range. It's not really worth arguing about. Build one and let us know what you think about it. So far it hasn't really seemed much different than 8190 for me, but I didn't find much improvement in BCY X over 8125G except making my wallet thinner.
