Wow - thank you guys, you've given me some great ideas! My Zenith came in today and I love it compared to the Nautilus 2. I'm using the pre-installed coil, and I've read on other threads, it takes a break in period for that coil. I'm getting decent flavor, vaping at 14W and a little airier than I normally like it. I'll keep vaping on it, but I do like a warmer vape, and I did pick up extra 0.8 ohm coils.
S&S - I think I'll pick up 2 of the mega tanks you linked to and some of the 0.5 ohm coils - for that price, I really can't lose, even if I end up not liking it, but it has some good reviews.
I also did order a couple of the Uwell Crown tanks. I actually had accidentally ordered the 2ml version of the Crown III and was a little mad at myself, because I had wanted the 4 ml version.
I need to stop - I think I'm well stocked, as well with my Ahlusion juices - which I adore - that's who I purchased from before. Enjoying some Mango Lassi in the Zenith this evening.
