The leaders I was asking about have those rings for tying (looping) on
tippets.

In the past, I've usually used mono leaders that are fairly heavy.
Sometimes a 2X or 3X mono leader on a 4wt or 5wt rod. *I usually use 5x
or 6x flouro tippet. *Leader turns over OK but sometimes creates a
pretty good hinge at the tippet.

If you want to avoid hinging at the ring, then you must use tippet of
the appropriate diameter ( and/or stiffness), and knot it. For this
reason, some people superglue ( cyanoacrylate glue) the knots as well.

For a number of applications,( slack line nymphing for instance, with
or without an indicator) lighter tippet which hinges at a right angle
is beneficial in reaching depth more quickly and gives better
indication. You need to use a tuck cast with such leaders to PREVENT
them straightening out at presentation.

For dry fly fishing, you need the right tippet to enable power
transfer and turnover. Stepping down if required. If the tippet you
use is too light, or merely looped, then it will hings, and power
transfer is also badly affected.
