Oh I have gone down my own sets of rabbit holes along the way myself. I was rebuilding string clearo's and protanks before rebuilding was a thing. LOL
Mike and I, I think are the main technical oriented vapers left on the porches.
These days I am mostly focused on getting my ducks in final order for the coming vapocalypse and trying to fight down the sick feeling in the pit of my stomach that this is going to be even worse than we have envisioned for all these years.
Being in my mid 50s I am one of the younguns on this thread. I am aiming my prep at an optimistic 40 years. Big task. Lots of time for things to go horribly wrong.
My primary vaping preference is squonking but even so I have several rebuildable tanks and mods to put them on as well as more standard dripping attys. Not a fan of old school dripping but if that is all I am left with so be it. It is better than smoking. Heck I even have Divers so I can put my old carto tanks back into the rotation if that becomes necessary. I hope it doesn't come to that those things are a leaky mess but they could be made to work.
I made it my business more than 6 years ago to begin prepping for what is happening now. Learned what I needed to to build safely and make liquids. Heck I even have printed instructions for how to build my own mod and atty should I have to (God please don't let me have to).
I think what we are seeing now is BTs long gameplan to put everything but them out of business. I have no pity for Juul. THey sold us out long ago before they were bought out by BT. There never was a path for our kind of vaping going forward. I just worry so much for those still smoking.
