Well, I think you're still giving the MFLB a bum rap on the whole "tolerance" thing. Interesting reading in my thread about a t-break. Plus, some additional new commentary, you might not have seen, if you have read it.
I think my experience just from a single day reversal, from switching back to the MFLB... and the rest of the commentary is a pretty compelling argument for me. Plus, the Biochemist buddy that chimes in, 3rd party and my own father, who is a Biochemist also. I'm sure some peoples' bodies might react more strongly towards actives released at higher temps and they think the MFLB can't deliver them, but with the right technique... you can even pull those off (with batteries even).
I'll repeat it until I'm blue in the face. The MFLB is what you, the person makes of it. You want it to be a Bubbler Bomb, it can be one. An e-cig, it can be one. Just take the time, to master the ones you can. Its not a Jack of all trades and Master of none... it actually can pull off mastering a few of 'em. That's more than you can say for a lot of vapes. Heck, the Pax comparison, really opened my eyes to that. Thicker, more satisfying vapor? Horse poopie! I knew it, but I never really put it to great thought. It was my daily driver for a long time and my need to expand had nothing to do with a physical need for more. It was purely, being stricken with the same crap a lot of people do around here. I won't say its name, since maybe its just a phase. No jinxies.
However, ultimately... to each, his own... eh? Cheers!
