Knowing that taste is subjective and influenced in many ways, I use the same mod and atomizer to get an initial, then I test, etc. In the end I have a spreadsheet that covers flavors. I am currently just doing fruits and with that in mind, I found 5 different plain apples and I will order each for comparison.
I know it might sound silly, but finding a good blueberry or cherry vape is what my hobby is all about. I imagine I will be doing this for years, so why not.
I WILL find my happiness!
Have you looked at vaporbomb? Their pg/VG ratios are selectable....and their green apple and black cherry flavors are excellent IMO
