I have quite a few flies that have been smooshed a bit here and crunched a bit there. They just don't have that freshly tied or bought look to them any more. How important is it to protect hackles and the overall appearance of a fly for it to be effective in the fish catching department? Is there a way to get flies back into shape once they've either caught enough fish, or have been in the same spot in the same fly box for far too long? How careful are you with how your flies are stored and transported?
