I'm in a similar stage as you, vaping tv's Kretek 80/20 to replace clove djarum blacks I use an ego-k (1100 mah, 4.2v) and the LR 1.5 ohm ego mega dual coil cartos, all from tasty vapor (they're my local/retail store). The emdcc's with kretek lasted over a week for me, but I think I burnt my 1st carto after a week from user error/not keeping it wet enough so I switched out to a new carto and it's working fine again. I did switch from the kretek to tv's mojito for my all-day vape now, but the emdcc's work well with all the 80.20 flavors I've tried from tv.
