Agreed! I haven't seen any 24 mm RDA with top airflow either. Only 22 mm RDAs.At that size, I've really only seen side or bottom airflow
The Sapor is a pretty good RDA. However, both of the once I got, are leaking a bit through the 510.Thanks. I like the Buddha but a little expensive. I am going to check out the Herkales, and the Sapor. Building on the Sapor will be the same as my Troll.
