I'm new to TC. Only using it for the last few days on my hcigar Vt inbox. Using a 0.9ohm SS coil, I'm finding my sweet spot somewhere around 330 F with excellent flavor, vapor and warmth. I'm using the default profiles except that I bumped preheat to 55W. I notice that most are setting temp. to 400-450, which makes me wonder if I'm missing something? Nothing to complain about. Actually happy to be enjoying the vape at lower temps, but just wondering why the big difference.
