I don't know about spitting, but the flavor was just overwhelming... I think that was the main reason to keep it aside for now. Airflow was a bit high for me, but it was the flavor which was too much. Could be because I am using nichrome for the first time?
Hmm, sounds like you should try the 1.5 coil. It would give you some vapor at lower wattage. The flavor is sort of intense on this tank, even with that coil, but I love it for that reason. Coming from the Cubis, I could totally see it being too much, since the Cubis is um...at the other end of the flavor spectrum. *no flavor cough*
But it's all about preference, so stick with what's working for you. If you do want to try a 1.5 coil to salvage the tank, I think myvaporstore sells them individually, so you don't have to try a 5pack.
