boochips, I can't really give a proper estimate because I never let it dry out too much. I suspect that it won't be too much of a concern for you since you're using a pen grip which allows you to drip a few drops every hour or so (or as needed). I think the general estimation is a few hours at 6v.
I usually vape three flavors throughout the day: marlbo, ry4, and flue-cured. Each cartomizer will be fully loaded in the morning, using Taryn's spin method (it's a sticky in the V4L subforum). All three usually last me can last me a good 8 hrs without any problems (but I think I would consider myself a moderate vaper). On most occasions, I top off frequently, and don't really worry about refilling.
I'm sorry, I know I didn't answer your question. Hopefully someone else can give a proper estimation.
SKYY, I apologize for the lack of clarity. I should have said SB and BB PT at 6v and 5v, respectively.
