Hi guys I'm trying to make a decision between these 2. At the moment I have a mPT3, an iClear 30B (which I never use) and 2 Twisp Clearomisers. I know if I get the Aerotank I can keep my coils unified, but I am very curious about the BVC (which is expensive) for the Nautilus. Any advice? Also, thanks to SkyBlue Vaping for my speedy delivery in a purple giftwrapped bag this morning
