Exactly my thoughts. I don't mind taking risks with my flies casting them near to the bank or trees and losing a few on an outing. Makes more room in my box for tying more.I use white veevus GSP thread more than anything else as the majority of it gets covered by materials to make the fly. I have a bunch of sharpies to either blend the final wraps or to make a hot spot (red, florescent orange, chartreuse). I've not seen any fading during fishing the flies, but like already alluded to, I will likely lose a fly way before any noticeable loss in color.
