And I'm willing to bet you've never had a problem with dropping out of tc with spaced winds within the res range of the VT? It's not really possible with a spaced coil to get varying res changes as long as the connections are solid. I've been in vaping bliss with spaced Ti builds for weeks. Also, I think Ti builds are less likely to jump out of tc because of the lower tcr values even with .2 ohm builds. I started using Ti over Ni200 for the durability but the benifits may prove to be more beneficial than originally thought; the Ti coils dryburn to near perfect cleanliness. After 9 dryburns and well over 200ml of Naturally Extracted Tobacco juice (dirty as hell) ; see pics for kanthal vs. Ti builds:

24g Kanthal .25 ohm dual coil build. 2.8mm spaced. Running at 35w per coil in my Plume Veil rda.

26g Ti .20 ohm build. 2.8mm spaced. Running at 30-35w in tc on my STmini at 520°f.
Illustrated here is the difference in coil pitting and scale deposits on Ti vs. the kanthal arrangement after 9 dryburns and over 200ml of net juice. That shown, I have to admit I've not run out Ni200 builds to this level of endurance as Ni200 just seems too flimsy for my liking; couldn't wick it heavy enough for speedy juice transport without distorting the coil . The 26g G1-Ti so far has been flawless, and with proper rinsing with water after dryburning at 25w seems to prove effective for removing juice deposit accumulation and doesn't seem to add excessive pitting or corrosion as with kanthal.
