Your leader and tippet is the only thing between you and the fly.
Using a high quality leader of the right size to turn over your nymph or dry fly can be the difference between success or failure in hooking your trophy trout.
You can use an expensive top of line brand or our Stone Creek reasonably priced leaders.
The trout doesn't care but your wallet sure does.
Our Stone Creek leaders come in 7 1/2 ft 3X through 6X and 9 ft 2X through 7X.
Stone Creek monofilament leaders come with a perfection loop at the butt end for easy attachment to you're fly line.
