SS TC is going to be problematic for quite some time, because nobody has settled on a "standard" for the stainless itself (304, 317, 430, etc), and while a handful of mods have exposed user configurable TCR settings so you can tinker with different grades, most rely on presets (and the mass market WANTS simple presets, not more complexity). The variance in performance between the different grades can be significant, there is no "one size fits all" preset for stainless steel wire.
With titanium, Grade 1 is Grade 1 is Grade 1, so Ti presets should just work (provided the board maker did their job properly). Same with "pure" Ni200.
Thanks!
Ti it is then...
