One is a small regulated mod (Provari) with a tank used mostly when I'm out and about. The other is an 18650 mechanical mod (Silver Bullet) with a rebuildable dripper that I can easily change up flavors when I'm home.
That's pretty much where i am at too. Provari 2.5 with kfl+ (a couple for now since i still switch flavours all the time) for out and about, and then a hex ohm v2 with my dripper. I will probably get a hex ohm 2.1 tomorrow, just to have 2 drip flavours going at a time. I know there are more advanced boxes out there but i do like the form factor, the buttons, that its made by people down in austin.
The istick 30 I will likely hand on to someone starting out.
Still have 2 sigelei minis and 2 subtank minis that are getting way less use now, those will get boxed up soon i think or kept clean and empty in case i get lazy going out 1 day lol.
I did order a couple of sigelei 150ws, the price is so good right now and after some testing I will keep them packed up or maybe i guess use all 4 in rotation? The main point of the 150s is just a backup and a little addition to my vapocalypse pile.
So asides from this weeks hex ohm purchase, I should be good for a long time. Maybe depending on how regulation is looking i may grab a couple more but i will wait and see.
Anyways... Have as many as make you happy i say
