I hadn't spent too much time with the TC on the Evic. I had tried the Ego One Mega tank when I first got it, but had a cold and chose a liquid that had a higher PG level just because I had a cold and wasn't too impressed. The flavor was off, a bit harsher than I was used to, so I blamed that on the tank and my experimentation and/or lack of TC knowledge.
I had picked the tank up again a few weeks later, only to discover it was flooded. Just like any tank, if you let it sit too long without use, it will leak and flood. So I poured out the liquid and rinsed it out, coil and all. I wasn't certain if I was going to use it again (the tank, not the Evic VT). In the meantime, I've been reading through the posts and have come to a better understanding of the controls and settings for a better experience.
Tonight I loaded up the same nickle coil in the tank with a tastier liquid (a 50/50 blend), and it's been performing quite well. Found a sweet spot with 35W and 490F. Much better consistency, vapor production and solid flavor. The Ego One Mega is still way too noisy. So I feel better knowing that the tank, and the whole TC option, isn't a total loss.
Thanks for the insight to the titanium coils; that'll come in handy when I'm ready to test that one out.
