Sorry - apparently I've neglected my own
thread!
I have the Limitless Plus, and yes, the Griffin tip fits. Sadly, it does not fit into the Gold edition. I bought the Gold edition for my brother, as the Plus is no longer available around here. Seems that Limitless and IJoy broke off their partnership, at least as it pertains to the production of this RDTA.
Cosmic, to answer your question, I'm not a fan of the added bottom airflow.. it gives me spray. I don't believe there's a way to turn it off without modifying the atty in some way (could tape the intake holes..)
