I'm not sure how much I can help, but to clear up what you are looking for so others may offer better help....
As far as a "mod that just works in TC", I have tried TC on 6 different mods and the only one that gives me a vape I like is on the Lavabox DNA200. Everything else seems to be a bit of hit or miss to me. Therefore, I only use one TC set-up and all my other tanks and mods stay with power mode. But I must mention that I have only used factory TC coils and not sure if I will ever try building my own.
Then you say you want a mod the will "last." If you mean "will last" specific to TC, I don't have the experience to help you there. Only thing I can say is the Lavabox I have uses a build in battery, but I bought it because you can buy/replace it. Given an opportunity, I would part with it. If you mean a mod that won't crap out on you, that seems to be a luck of the draw for most mods. There are a plethora of choices right now depending on individual tastes and I believe the odds are pretty good most will have a decent life span.
