I've read, "don't lap Talley LW's!"...
I try not to overthink them. Are they gorgeous examples of old-world craftsmanship, perfect in form and function, beyond reproach? No. But they are very light, very strong, as simple as is possible, and have been the most "low drama" rings I personally have used.
I've sold several scopes here on the Fire that had been mounted in Talkey LW's. I haven't seen them leave a mark yet.
I have some Warne rings, pretty sure they are Warne, that you have to "snap" the top ring down over the tube. Gives me the heebie jeebies every time.
