Looks great to me there will be a tiny little singe and that's no big deal, it's working for that build perfectly.
More complex builds like Aliens etc will require some tinkering and not all SS316L is the same, it differs between manufacturers. Just more tweaking or stick with wire that's working for you. I use a lot of SS430 Unkamen 28g (twisted up) or Zivipf (All gauges available) as it has zero nickel and a higher TCR value than SS316L. Titanium Grade 1 and NiFeThal 70 or 48 (sometimes labeled as 30 and 52) are exceptional for TC as well, if you are looking to venture down other wire paths.
Glad to see you are having a good experience with it. I love TC with RDA's as I am a lazy dripper/squonker and it's saved me a few times.
