I was a bit disappointed with the Lavatube at first not working well with dualcoils. After looking at the posts here at ECF I found a few stating that single coils cartos work great too. I have been using the
Phoenix Bottom Coil Clear Cartomizers from GotVapes.com. They are aprox $11 bucks for 5 of them.
I have to say they are awsome!
By the way, did you get the 2.4-2.6 or the 2.6-2.8?
