Tallulah, I started dripping on my super mini two weeks ago. The pen style holds a lot more juice in the cart than a super mini, so the advantages of dripping may not be as great in your case.
However, I'll be buying a pen style very soon and plan to continue dripping. Reason being that it's easier to keep track of exactly how much nicotine I'm taking in. General consensus round here seems to be that two to three drops on the atomiser is about equivalent of one cigarette.
On my super mini, dripping also produces a lot more vapour than using the carts. That may be different on the pen style, but I'm not sure. Others will probably be able to expand more on that.
