The 6ml Surge Atty Tank on a Joye Ego
surge on GLV 2 XL. It went great on my darwin when I still had it. It makes any mod a bottom feeder. It is a must have IMHO. You can read more about the surge and how to get one here. Hopefully GoodeJuice will carry them soon so you can get them with their great Tobacco Extracts, or maybe Virgin Vapors will carry them soon so you can get one with the amazing desert and fruit flavors their. But until then you can get them only here. (unfortunately they are almost always out of stock) but they are getting shipments soon.
