I'm not a regular TC vaper but occasionally use TC for very restricted RDL vaping with a few atomisers that I use for TC only - always with spaced SS316Lround wire at or above 0.40 Ohms. I don't trust myself using any TC wire like Titanium or Ni200 as I'm absent minded and don't want to risk accidentally vape a TC only build in Wattage mode.
Most of my vaping is relatively high powered DL using low ohm complex builds, when I vape MTL I generally use MTL fused claptons or MTL staples - and TC doesn't seem to work well for me using these builds so I stick with wattage mode. I'm guessing the combination of different gauge wires that possibly ramp up at different speeds and, for low Ohm DL, a minimal increase in resistance when heated makes it difficult for even a sophisticated board to accurately assess the temperature and respond in time.
The only current member I can think of that vapes TC regularly is
@ZenAnarchi , who can probably give a more informed opinion - looking at the stats of my Ultroner Thor DNA75C on Escribe it has over 60,000 hits, only 330 have been in TC mode...
