I feel so bad for you folks with first run TGT clones (brass decks), what a bummer. I'm so glad I waited, I could never afford the authentic. To the designer(s), if you come around Austin for the Grand Prix race track, SXSW, or ACL, (a few) drinks are on me!
I don't know about other wicking options, but I used organic cotton ball for wick and a 2mm ID "micro"ish coil. 28g, (wraps?, meh) 1.2 ohm running at 4 volts. Fantastmagoric. If there's a downside to the TGT, I haven't found it yet. More sympathy goes out to those that vape tank cracker juices.
IMO, the SQuape is very similar the TGT in many ways though, the same coil and wick give me the same vape. One is much heavier in weight though quicker/easier to build and has more capacity (SQuape), the other is has many more parts but is much lighter and generally looks better (YMMV). To both of these, the Kayfun styles are over engineered to a fault. This game is moving fast, the next king has some big shoes to fill.
