I'm a big fan of flavor so maybe my next order I'll try 70PG/30PG. My recent orders don't give an option. Space Jam Robo Fuel and Uncle Junk's Genius Juice are as is.
I had the same dilemma, what percentage??? GOSH! Sometimes there are too many decisions!
My B&M where I "got my start" (2nd B&M I tried and they were a CLEAR winner for customer service, listening to what I wanted and gauging my habits as I went back. They make their own and it was "pretty good" (had never had any before! LOL) and they had ONLY a "house blend of 60/40". I did not even know to ask about the blend when I first went in and started buying! Even though I had been doing my research on this forum. That shows you how much all the info can fly in one ear and out the other! So when I got to finally ordering juice online, what do I do(??? very puzzled) Well I liked the flavors I picked in 60/40 and a copius amount of vapor is very important to me, I didn't enjoy cigarettes when I couldn't see the smoke either! The more the better. So I learned here that VG is responsible for vapor production, PG can carry flavor better, I just went with 50/50 (giving me ...maybe... 10% more vapor).
I suggest you find #1 (NUMBER 1! for me anyway) *juices that you LIKE or love* as your very first concern. Go for anything that's like 80/20, 70/30, 60/40 or 50/50 in the beginning. Once you find some juices that are ADVs for you (all day vape--something you don't want to put down, lol) THEN go back to the same vendor and get THAT juice, that same amount of nicotine in a different blend. But to me LOVING a few juices and having some "plan B" juice flavors that you like, that would be the first.
Another thing I did (after I'd already ordered everything in 50/50, lol) there were some I sort of liked but felt they could be a bit better so I would check the webpage for the place and see if they listed it or a customer service email to them to find out:
what blend do YOU recommend for your juices?
