Wotofo was released a new Serpent: The Serpent Alto Biggest news is the build deck - it now sports a Merlin/Goblin V3/Ammit design: Overall height is a little shorter with a finned top cap. Juice capacity is down from 3.0 to 2.5ml I love the new deck, but looks like now there is only one airflow hole - compared to two on the Mini. I'm wondering how much, if any, that will reduce the overall airflow. One review I came across reported the airflow to be about the same - we'll see I guess. I dislike the the new top cap but it looks like an original Mini top cap would be compatible.
