I never quite understood the appeal of the SSV. In fact, I have one sitting in the corner of my closet, waiting to be sold. I got the Plenty to replace the SSV primarily because it puts out more vapor without the risk of combustion. In order to get big hits off the SSV, I'd have to crank the heat and stir constantly, and sometimes I'd end up combusting the bowl. Maybe I never quite got the technique for it, but I never liked it.
