Re: No-Knot Fas-Snap, have you ever used it?
You still tie a knot to attach that to your tippet. I tried something similar many years ago. I think Cortland sold what I tried, but same idea. They were OK, but as Silver Creek has pointed out, if you fish with a wide range of fly sizes, it's not the ideal connection for all. My main issue when I tried them was losing both the snaps & my flies to snags. At least with just the fly, the loss was not as costly.
