Interesting finds! The first one is somewhat similar to my path.
I think it's time for me to share it.
The MSLS gives us several eliminations and placements, the most interesting one being 9r4c3. Then:

(89=3)r3c5 – 3r2c6 = (3–89)r2c8 = ERs(89r6b3\r3c59) – Loop => –3r1c6, –1r2c8, stte
(I like to see it as a 1-cell exocet, whichever digit appears in r3c5 is forced into r2c8)
As I've said, the original is still tough after that and the rest of my path for it is not that beautiful.
