Spent many $$$ a few years ago. Tried extraction also. Many base flavors, TA, additives and various formulations. I was able to top many ready made products but never got to level of tobacco flavors from vendors such as alien visions, halo, indigo, johnsons, etc. Just not a tooty fruity kind of vaper......smoked analogs about 30 years insurance increase made me give up....vaping ever since. "Ask the Veterans" on the board made few flavor suggestions, but also suggested asking the question here. I became a Boba's fan ~4 years ago, laid off it for a few years but after trying my own blends and others plus premades I'm curently back on the Bobas and vape it like mad. Thanks in advance.
