I currently mix my own liquids and love Butterfly Bait and Tobacco Praze (going to test othets soon!)
Question is, unlike other eliquids I find that I cannot vape them above 3.5 to 4 volts or over 5.5 watts as I get a sour flavour.
Use the eliquid in Kayfuns, Ithaka, protanks, iclears and Unitanks and with Vamos(various) and a few mods...all the same!?
I used to put Butterfly Bait through an Orion with coils between .9 and 1.2 ohms and through 1.8 to 2 ohm Boges/Smoktechs using stacked Tenergies (shhh! don't try that at home) without a sour taste at all.
Doesn't answer your question, but maybe there are (an) other factor(s) involved.
A hug is like a strangle you haven't finished yet.
I don't really know! Someone else said thus, but cant fid it.
Tried different bases - nic, pg, VG and used different % mixes.
it must be my old nackered taste buds.....
