I've tried that company. I've used Mocha Java Smooth, Grape Vape, No Bake Cake, Mango Martini, and Mountain Dude. My favorite was the Mountain Dude, a lemon lime flavor similar to Mountain Dew. I ordered them in a 50/50 pg/vg ratio.
Not really sure it matters what pg/vg ratio you get as long as you are not sensitive to pg. It's said pg carries flavor more, and vg produces more vapor, together they make a great mix. If you prefer flavor or vapor more, go a little heavier in that direction. Nicotine strength is what provides a throat hit like an analog. Since I started vaping 9 months ago, I've cut my nic. strength from 24mg down to 12mg. Will probably stay there.
