I have reading of nothing but good things about that tank. I am not sure what is going on with the Billows but no matter what build, wick material or method I use, it keeps dry hitting if I take consecutive hits. If I do a non powered hit first then fire it its ok but thats not how its suppose to work. I have tried 2 mm, 2.5 mm... SS, TI, NI, all sorts of wicking, using low power etc. at around 30 watts I can get it to work and keep up but the vape if very anemic. Typically around 36 watts has given me great results in the past but recently it has become a royal PITA so I am going to try the Crius. It looks like a real potential winner.
