Can't say much for the smok as I'm not using it but my current setup is an ipd2 with a goblin mini. The GM has ridiculously big airhole and it makes for a smooth pillowy vape (good for lung hit imo) And as the others have already said, it's a bit PITA to rebuilt as the deck is quite small and is very picky for good wicking techniques. Just rebuilt my coil yesterday night and it's leaking after every vape session today (my fault really, put too much wick into the coil and clogged up the coils) will probably rewick as soon as my tank empties.
