I’m a LL guy (level line) and you get to use what ever line you want without critique from me.
I do use tippet rings on all my lines. It serves two reasons well. It keeps my line at a consistent length across all my rods.
Consistency.
I use a clinch knot on the same premium tippet. Not an improved clinch knot, a simple clinch knot. Pulling the knot tight generates friction so I wet the knot with my tongue before snugging it down. If I snug it down before I wet it, the knot, where it is twisted becomes hot and it greatly weakens.
It is a step that must not be skipped.
I don’t read much about people wetting their knots before setting. It’s not a myth, it is real and I surmise that this omitted step is reason for a lot of lost fish, that and poor choice of tippet brand and it’s old or has not been stored properly.
I use 5,6 and 7x. All on tippet rings. Same brand, same knot, same wet before cinching down, no problems. Same methodical approach at the kebari. I use silk bead cord, same brand, size etc.
My knots break when I expect them to. Occasionally the tippet will break in between the knots, most of the time which is rare and expected, it breaks at the fly where I want.
That’s whatI want.
Where it breaks, it is consistent, and the tippet gets inspected and I nip a quarter inch off the distal tip and re-tie my fly on.
Tippet rings give me consistency at little or no compromise.
I don’t like them because they are an extra step in line making but worth it. My lines last longer, stay the same length and the weak point in my system is at the fly, where I want it.
That being said, it’s the consistency and repetition that allow me to cast flys larger than normal, although that is something I rarely do.
Buy what you want, use what you want. Choose to follow advice from who you want. It’s up to you to make your own choices.
Have fun and take care.
