I have learned so much on this forum. But I have 1 question I haven't seen much on. What is the best way to handle the ecig? Laying flat or standing up vertical. If it's vertical, should it be LED end down or cart end down? I have a Pilot 401 and a Classic on the way. So far I've been keeping it laying flat and all seems well but I've seen pics of people putting it their pockets.
