Right now enjoying the kayfun mini 2.1 es with ekowool/kanthal set up. On my AC9 and ZAP, I've been using 400 ss unoxidized wick with either 28 or 30g Kanthal A-1 coil depending upon which mod I'm going to use for the day (VV or mech). I have the AGA T+, Igo L and Igo S on standby at the moment but have enjoyed those too.
