I've been lurking around this thread for a good long while now and figure it is time to contribute.
After several years of farting around but not entirely committing to an Atmos pen with Omicron cartos, I broke my dab rig and decided that I no longer had room in my life for elaborate, expensive, fragile glass.
After about 3 hours of only using the Atmos and Omicron cartos, I was fed up with the crummy hits and the constant fight to not clog, but keep my concentrate thin so I could pull my measly hits out of the carto.
Took a trip, and picked up a SToK pen, which was discounted for the day so I didn't really bat an eye when they proposed it. This device is a non-vv battery that came with an atomizer with a ceramic inlay and 30 or 32 gauge wrapped around some silica.
This guy was adequate, but didn't deliver the 'nail' hit I was looking for. Also, charging was exclusive of using, so if the battery was fried... I wasn't.
I upgraded from there to an iTaste vv v3, and a Catarpillar RDA and started building my own coils and devising my own rig, instead of trying to buy something out of the box as that was clearly not giving me the results I was seeking.
The combo was good. I realized I don't like using wicks for concentrates whatsoever. After that realization, I started building coils that would hopefully eliminate my need for wicking as much as possible, which led to some coil-over-coil builds that the 11w iTaste vv v3 just couldn't push.
I now sit with a fake-ass HanaMod 30w with the same Catarpillar RDA but a new coil setup @ .8ohms/30W and am a happy man. That said- I do not use a wick, and do have to spend a little time every day re-claiming some oil splatter. I prefer it that way... probably not in the overwhelming majority in that statement.
Without further ado-- my rig:
Twisted 30g in a stacked skillet configuration. The top skillet is where I place the dab. It heats and melts the dab to the bottom skillet, which heats faster than the top, thanks to the fact that the top is burdened with melting the concentrate.
This coil is about 3 months old and has seen repeated abuse on the daily so I make no apologies for the current aesthetics. On top of that, I just used it to melt down probably a quarter-gram of shatter dust that I haven't entirely reclaimed as you can see. That's one of the nice things about this, too-- put shatter/cruble/wax/whatever dust in the well away from the coil, close it up and heat it to melt and homogenize your leftovers.
In those 3 months, this coil has probably vaped through, I dunno, like 12-16 grams?
