That dotMod squonk mod looks like it would be great for nic juice. Might have to pick one up. Currently use Vandy's Pulse mod. It's a little messy, like most squonkers (the dotMod has a better squonk connection). Also used an earlier version of the Pulse RDA for nic juice and went through a wickless phase. Wicked still works better, IMO. Another possibility is Vandy's Maze RDA, coil-less, but still uses a wick.
You will probably need to thin your rosin-based concentrate significantly to work in this sort of set up. They're designed for thinner nic-juice, and provide some resistance when squeezing the silicone bottle to load. That resistance could well be too much for thick cannabis oil.
There doesn't seem to be any consensus on the best way to thin - all have drawbacks. The options, AFAIK, are glycols (PEG. PG), terpenes, MCT oil, or some combination. With glycols, you'll need to use PEG for a relatively concentrated oil. Many find the flavor of PEG to be disagreeable. Some have reported using just PG at higher dilutions. IME, concentrate won't dissolve in VG at all - even a drop of VG in the mix will pull it out of solution.
Terpenes seem like a better solution, because cannabis already has lots of terpenes. You need to be careful - one terp supplier has apparently been selling a product that contains no terpenes whatsoever. (It's probably just mineral oil.) Also, it's easy to use too much - terpenes may be harmful, or at least irritating, in larger doses.
1:1 MCT oil might be worth a try - at carefully controlled temps below its smoke point. Keep meaning to try, but at this point, content with LAYG one-hitter options. Not much incentive to waste concentrate - which will very likely happen, if you try to get any of these methods to work.
Man - time limit expired while writing. Gotta love copy and paste.
Just noticed
@NimbusVapor listed their Hercules in the classifieds thread. This is older tech, but it does what you want. You can load it with oil and hit it repeatedly. (Thought about reproducing their stealth set-up, in the past.) The manufacturer vanished, and the Herc has a bunch of tiny parts - as well as a learning curve, but many owners swear by them. (Looking at you,
@PPN.)
