I'm looking to get me an RBA. I have a few RDAs and I love them. I'm looking at the Kraken, Russian 91, and the Kayfun lite. What do y'all think is the best? I like an airy pull and good flavor. Also like to blow clouds, but not as vital as the flavor. It's doesn't have to be one of these. All RBA r under consideration. Let me know what y'all think. Thanks VT family.
