I've been using Kanger T3's which are like 2.3-2.5 ohm and I want something similar for the carto+tank setup I'm putting together. I don't have any experience with cartos so I was wondering what you guys use? LR seems like something you'd use on a non-VV PV and the SR's I've been seeing are up around 3.0 ohm which I would think is too high for a Twist. I want to take advantage of the 5 pack deal at surevapes but I don't want to order the wrong thing. Is this something I'm going to have to experiment with by ordering a box of each?
