Thanks for all the input about the bad taste...it may be that soaking will help, certainly didn't hurt 
Re: the Vamo.
Not very good picture sorry, but I show one with a Davide and one with a ProTank. The Davide is with the chrome beauty ring and 510/eGo adapter.
I just got the Air Flow Controllers and like the looks better, but didn't notice any difference in the draw using these tanks. I suspect not much restriction in air control due to the particular design.
