As a change, I own a Twist……and I haven't used that tank. The price is attractive, but I kind think it's hands-down uglier than everything else I've put on my twist………but for $7, I might think about it.
What I have used……
I've used a Vivi Nova for about a week. At first, I kinda hated it. But I'm getting used to it. The draw is very different……not at all like carto tanks or attys……feels more like a decent/good (but not great) pipe that's been very well packed. Flavor is decent……if anything, they lack in sensation of "doing anything." It's not as up-front as cartos. It almost feels like I'm not drawing in anything……not even air 'till I stop and breathe in. At this point, that's my only complaint. It feels weird. On Tuesday, I was ready to throw it in the trash…and kept not wanting to throw out the juice that was in it……and kept refilling it out of laziness for fixing smoktech's shotty punching on their "resurrectors".
I used (single coil) cartos in a Smoktech DCT for a while and really liked it. I still do, but the flavor is different between cartos and between cartos and everything else. It's an up-front thing…I feel like I'm actually drawing something other than just air, and there's more air in it to. So far, I can say I like boges better than smoktech, and smoktech's xl single coils better than the single coils that they make for tanks……so far, it seems the easier something is, the less taste there is.
I've used 901 and 510 attys for dripping, including a 510 that I debridged. That is what it is, but I'll keep doing it at home.
