Yeah I would try different combinations, including a MTL vape with much higher nic. If there are times you cannot be chain vaping, well, MTL devices can deliver more with less visible vapor, lots of folks who "prefer" DL at home take stealthier kits to work or use them when they don't want to be chain vaping all the time.
Then you have your sort of "middle of the road" vape situation where you are sub0ming, but maybe your resistances are slightly higher, you turn oown the wattage a bit, and well, that can be a valid strategy for someone who likes more vapor per puff, but also needs to tolerate higher nic, and not chain vape.
Good luck and welcome I'd suggest some playing around kind of a bit with everything. PG alone may solve your throat hit problem, but you sort of need higher nic if you want to drop the chain vaping, potentially.
Good luck,
Anna
