I have the Cylon and Battlestar. Both work really well in TC mode. Personally, I prefer to use manual TCR. For 316L stainless, I go anywhere between 0.00092 to 0.00098. A really good build for single coil is twisted 28g 316L. In my Siren 2 I have 8 3mm wraps which comes out around 0.6 ohms. I don't space twisted coils and it works really, really well. 420f @ around 30W.
I do space normal single wire coils though.
