I don't have both, only Cabeo, but from the pictures it seems that Kumo has got airflow from another SteamPipes, Corona.I'm thinking the same, lol. Removing the PEEK insert in the Cabeo turned it into an RDL, so maybe the Kumo is even more ideal?
I also have Corona, mtl 0.8 airflow, and it is good but nowhere near the flavor experience with Cabeo.
For me it's the adjustable mtl peek/airflow pins that make the Cabeo so unique.
