>>908077I wish I had a microscope and could see a real cross section of the different types of line. The only advantage SpiderWire Stealth Braid has is it seems to be a tiny bit smoother and more flexible (at least more flexible when new, PowerPro softens up once you use it a bit) but for the amount that it frays on me I will gladly take PowerPro over it especially considering they are about the same price.
