I agree with the "slight peppery" comment, though in my experience it's barely there. I have to look for it when vaping. The flavoring in every juice (and I prefer mild flavored juices) has overpowered that flavor. Also, it's not unpleasant, just "there".
I disagree with the throat hit comment. In my experience, the mix of the vape fluid has always impacted it far, far, far more than nic level. 36/mg @ 80% PG and 20% VG feels the same to me (in terms of TH) as 12/mg @ 80/20. 36/mg @ 80/20 has FAR more TH than 36/mg @ 60/40. So while nic MIGHT affect throat hit, the effect is SO tiny in my experience that I wouldn't even worry about it. Air temps have affected my vapes more than the nic content.
