Flave 24mm RDA (or some other single coilers)

[Train2]

Anyone moved on to MTL or boros - who's ready to let their old Alliancetech Flave go?
Not the 22mm, I'm looking for the 24 mm original.
Or perhaps an "Evo".
Picture for example

Also will consider other rda's with the following preferences:

• Single coil
• 810 tip compatible, or wide-bore tip, or flat cap
  (I have 510 tips that are fat/wide-bore, but need a flat top cap)
• Fairly "open" airflow

(Striborg? Jenna? Vauban? Airlab maybe?)
