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.
I am so glad that I asked you guys the experts, since nobody in the BPS reviews mentioned about the using them with different tippet size.
I guess to be able to effectively and efficiently using one of these is to stick with the same tippet material for the longest time.
I don't do dry fly much, for trouts I am mostly using leeches and wolly buggers size 8-12 with ±30" 4x fluorocarbon tippet loop to loop to the leader. I don't often change my tippet unless it is ±16" short and I can feel the abrasion in it.
This might work for me but hopefully I can get more inputs about them form the others.
my dad broke his finger a few summers back and and wasn't able
to tie any knots so i brought some up for him to try. they seemed
to work ok. he was able to switch patterns with out having me re-tie
