huge.. glad to see this threads still alive..

Both valloon have thier pros and cons.. the valloon breaks as its glass, the valloon tastes a tad better, the volcano valve setup should last forever.. def give OG a look around.. the glass forum is a popular place over there..
j_db.. great link.. as Ive never used that gun but adjustable temp (otherwise most guns are two weak or get too hot) and ceramic heater element are a must IMO..
Caligrower.. your gonna love VRIPPING! Covert any bong to a vape! Id love to get a VCB to fit my glass on glass 18mm custom roor tube.. I hear they are a bit backed up in orders as of late.. some people ordered valloons from mark back in dec. and he's just now getting around to shipping them out.. so be prepaired for a little wait if you ordered a valloon.. they are also getting that o-ring for the valloon to fit on the volcano base unit..
In regards to your question..
Inhaling a huge hit of vapor will not be like the headrush of inhaling a huge cloud of bong smoke but still gives you that.. mmmm feeling... but without the lack of oxygen from coughing for a minute and half

Though the VRIP's have been known to fill up w/ some thick tastey vapor.. a def nice choice.. one of my top 3 vapes on the market.. along w/ the verdamper.. wish the volcano used water filtration to cool thier vapor!
