Wow, very very organized. I've ended up with a small wall filled with shelves & those organizer boxes to store All My Vaping Stuff as the years have passed, but when leaving the house I just toss a fresh battery into mod, make sure tank is topped up, stuff into pocket, and walk out the door.
I do keep loaded cartos, smoke juice, a mod that I've dropped like 15 times, battery chargers and random e-cig crap in dash of my car, but that's about it for backup.
Using Super T Precise', GGs, and ProVaris, all on 18650's, some voltage/wattage regulated, some just bare metal, with random tanks (BDV, VPX, Phiniac mostly), and the point of this post... for me, for whatever reason, Boge cartos are not nearly as good with Ms. T's, as the Smoktech 1.7Ω "Resurrectors".
No clue why. I do punch two holes for the heavier juices, but on a Boge I've basically got ... 1 good tank-full (3-5mL) with any given Ms. T's juice I smoke, refill #2 is okay, by #3, it's not kicking out much vapor anymore. The Smoktechs on the other hand just power through everything and keep going a lot longer.
I personally use Smoktech 1.7Ω cartos & tanks almost exclusively when vaping Ms. T's. Awesome flavor, great throat hit, overall a highly excellent experience.
Will rant about rebuildables when I have enough of them in my collection to compare 'em to something, that's a new area of experimentation for me and I know almost nothing at the moment.
The Boges may rock harder when not using tanks, but I dunno, since discovering tanks the only time I don't use 'em is when testing new flavors and deciding whether or not it's worth putting in a tank, or tossing to the back of the fridge.
So far as dual coils go ... I personally have found no advantage whatsoever over single coils. All the dcs do is kill my batts faster. No subjective improvement of vapor or flavor that I can detect. Your milage my vary.
Oh, yeah, forgot, [edit]: I'm usually at 'bout 7-8 watts, though some juices seem to really shine at around 10 (though this is rare for me).
