Shortest FC / PDB /ESC Stack?

Anyone got a good recommendation for a short, good FC+PDB/ESC stack? I'm hoping to keep it well below 14mm.

Lumenier Alpha comes to mind.

Sorry I should have mentioned I'm looking for 20mm. I ended up settling in the Nano Lux which you had replied to in another thread.
