I rotate a lot but my mainstays are iVape RY4 (totally addicted and don't know why) and a DIY Hangsen Tab Blend + Flavor Apprentice Double RY4. I can vape either or anytime anywhere.
I rotate my flavors a lot - but my main 2 ADVs are
GLV Deadly Sin 6mg
MEL Grey Matter 50/50 6 mg
Be warned - both will make you vape your face off
