Opinions from a newbie DIYer.....I find the nic unflavored from MyFreedomSmokes to be the easiest and most versatile that I have found. I ordered my flavorings the first time from MBV, but they are too diluted and have to use too much to quench my taste. Get concentrated or regular flavoring from one of the par for the course vendors, FA, Capellas, TFA, etc. and you will be much more satisfied. For me, the PG/VG ratio isn't as important. Meaning I get 60/40 or 70/30 unflavored and go to town. My vaping requirements don't include exact PG/VG ratio. Just some of my thoughts. Just like getting the setup for the first time, once you have the mixes in front of you, it will become like old hat.
