My rotation consist of FF2, Ti Vong S vapcap, and Haze V3. I've pretty much retired my og pax, and gifted my mflb. If I could only have one, it would be the haze. The biggest downsides are that its not on demand like vapcap and FF2. That is also a plus because you can just turn it on and use it. No muss no fuss. No technique no deep breaths thing just works. I only use it for dry material because ff2 is superior for concentrates, but its nice to have the option. I only use ss cans, no screens at all because it keeps everything very tidy. It cleans very quickly and easily. It has a 10 year warranty, and uses replaceable batteries. It allows you to be able to sit back and puff over a several minutes, 10, 15, even longer especially with two ovens ready to go. I'll start at level 1 and work my way up. It easy for novices to use so it great for group sessions. I use mine with fc-187 water tool from dhgate and eds tnt vong sold at puffitup, and on hazes own site. They have great customer support. I think it makes a solid foundation, and if you find you a need something a little more niche to compliment it at a later date, then so be it. Haze was selling the cheapest bundle for $130 during the black friday sale. I was gonna get a second one, but ended up taking advantage of vapcap sale instead. But seriously I was gonna get another one, because I would hate to be w/o it if I needed some warranty work done. 10 year warranty! How can you go wrong.
