i know what you mean when you say it was fun but a bit tight
i have 3 stm,s and i tend to rebuild the occ coils with 26-28awg as they have better air flow
the earlier rba deck with bottom juice channels was a bit of a pain to wick the later rba plus is much easier
when wicking the later rba deck like most do i put the wick through the coil pull it up vertical and slide the outer body down over the wick then trim the wick just above the can and tuck it down making sure the juice holes are covered but then fluff it a little so its not to thick around the holes
it wicks realy good no dry hits but just feels a tighter draw than the occ coils the flavor is better in the rba because it has the extra air space around the coil and wick and has more room to produce and develop the vapor before you suck it out
i have a couple of RDA,s on order but for now the stm,s keep me off the analogs
