i also started with aspire et-s and glass bdc vivi nova (my brother suggested that to me, he convinced me to vape).. wanted to order a nautilus then, when i started to read this thread..

ordered nautilus tanks, replacement coils (from the other site).. and an squape! for him last week: i'm convincing him to start with rbas now
about the "tobeco" kfl i own (sku 13539 with wide juice channels version): tried much wick at the beginning, because i thought it was going to flood (it was leaking, in fact, and getting some semi dry hits; juice with about 80% vg). error. the best not leaking build has less cotton; inspired by someone tips and pics from here (sorry, i don't remember who was), the cotton is fluffy on the juice channel, but not laying down ("8" setup) nor occupying the whole rest of the chamber. again, simpler is better.
about its air flow and whistle (well, i never noticed a whistle, maybe because removed the af screw immediately), haven't needed to drill it yet; but noticed the hole in the positive screw, above the insulator that weezy has described: it has better af when aligned to the air hole (i think), so i adjust the positive screw to match it (to test, you can introduce a wire into the lateral air hole, it should reach and get into the screw hole); there are 2 valid positions in a 360º screw round. dunno if it will be effective, but you could try before drilling.
i've received the taifun (now i have the three kings, kf, taifun, squape), still cleaning the base, and a bit scared of the taifun setup (even bought some mesh, just in case). also received a 3d (my first dripper). waiting for the ss quasar, igo-w, immortalizer and omega, but now i can start to taste my mixtures (will use ekowool, and will dry burn it and the coil when changing flavors, hope it is enough).
satisfied with this gear, but my mouth gets wet whenever i see your vapeporn. amazing collections you have. thanks for the pics!
