I highly recommend the SSV. For the price it'll beat the Vol any day.
Well, I'm not a Volcano fan, although I don't dispute the quality of it. In my experience (I own a herbalAire) you can get a reliable, effective bag vape that gives you direct draw as well, for a lot less money. But I don't really agree with your comparison of the SSV to the 'cano. I have the SSV and love it, but if you're interested in a bag vape the SSV is apples and oranges. And if you're just comparing on price, a $120 VaporCannon will beat the SSV any day. I think the SSV is the best analog whip vape on the market, but it won't be the best choice for everyone. As for the SSV shell getting warm, I don't find that to be the case at all. At least not warm to the point where handling it is an issue. It's a 4mm thick aluminum housing.
