Self-confessed MBV fanboy here. Just a point - all the flavors below were ordered in either 65/35 or 50/50 at 18mg and some had 1 flavor shot.
I love hawk sauce. I've vaped 30mls so far and just got in 50ml of it. It's close to an ADV for me - although I just got Razzle Dazzle and that has a similar flavor and seems just as vapeable - maybe it's a little fruitier and doesn't have the hint of menthol on the exhale like the hawk sauce, but it's good.
Ecto cooler seems like a regular favorite on the forums - I've not tried it.
Cucumber mint - a little on the weak side for me, I still have about 12ml left. It's a nice mild sweetish flavor, but I have other MBV
juice that I prefer to vape.
Blueberry - Not tried a straight up blueberry. Have got the Blue moo which has the same flavoring - very nice vape, smooth and fruity.
Other MBV flavors I would recommend would be Extreme ice (in your face menthol) moo
juice - like a strawberries and cream with the emphasis on a real creaminess on the inhale and exhale, cinnamon roll - tastes like a cinnamon roll all the way to the sweetness of the icing and finally pineapple upside down cake - really nice baked goods taste with a hint of sourness of the pineapple.
I'm on a MBV kick right now and have maybe 20 bottles of their
juice in various flavors / ratios and strengths - I just don't think you can go wrong with their quality, their choices, their prices, their shipping or their customer service.
