Since I'm n00b, I don't even know if the tank by itself makes any differences in flavor & vapor but my Smoktech Pyrex DCT has very little window (pyrex glass) so when I pour juice in, it gets little hard time to time. I've heard about Cirrus tanks, Kanger tanks. I don't think the tank makes any changes as long as they are all pyrex glass (doesnt get cracked when certain juice is being used..?) but I need extra tank anyways to switch the flavors. (right now I only have one with Halo Tribecca...nasty stuff...real nasty..) Recommend me some good tanks. Thanks in advance
