EightThumbs,

I personally seldom reuse a fly.

If I am fishing nymphs, then that means the fly has been dragging across the bottom (if you are fishing it right), hanging up on rocks, sticks, fish, whatever. Why reuse the fly another day and possibly loose a good fish because the point was a little dull or maybe stressed and will break.

Dry flying, well fewer rocks unless they are behind me on the shore and I don't realize I flicked the fly off one of them, or hanging up on a limb, fish, whatever.

I start every fishing day with a fresh leader and tippet, for that same reason. Why risk it? When you consider how much we pay for our fishing experiences, even if it is just the price of fuel to drive a couple hundred miles, why not give your fishing experience the best chance for a great day. New leader, new tippet, new flies.
