Heres some photos of ODY in Medium mode... The GGTS pictured is using a 16340 to be as small as possible... The mouthpiece is a little stubby but I kinda like it like that... This is done using the 2 tank pieces from the expansion pack and the stock ODY mouthpiece with the New GGTS/ODY base... (NEW GGTS/ODY BASE NOT NECESSARY but it sure looks cool) Keep in mind doing it this way does not stop the mouthpiece from coming all the way off the ceramic housing but some o-rings around the stem of the mouthpiece can be used as a catch or just be careful not to unscrew it all the way... and heres your GG PORN!!!
