I don't like the TH from nic liquids, the highest I go is 3mg in my EVOD, which is just right for a mild nic hit and nice vape. In the nautilus Mini and Subtank nano, I hate both the spicy TH you get from nicotine and I dislike the buzz also. The buzz from e-liquids with nic in (and I've tried a lot so had high grade and low grade both) is totally different from the feeling tobacco gives me. Same with the gum or the patch, it makes me feel nauseous and over stimulated and on edge. Tobacco made me feel relaxed and calm (but unhealthy.)
So I go for good flavour, dense vapour production and a TH based on warmth rather than the nic style TH.
@David Wolf - I tried to get a good MTL from subtanks but ended up finding the perfect and I mean perfect MTL experience from the Nautilus Mini, widest air hole around 15 watts for PG based liquids or around 16-18 watts for 50/50. The subtank with the 1.2 ohm coil and 2nd largest air hole was good for MTL but I still prefer the Nautilus MIni for MTL, in my opinion it is perfect for it.
