I'm not sure what you mean by loading up the vaporstar with weed that's "finished" in the volcano - if you turn the volcano's heat all the way up it can use up the weed pretty good. I don't even do that though, I just run each packing through a couple of times and then put it aside to cook with.

I just googled vaporstar and saw a demonstration video on their website. The thing with the vaporstar is that you're using a lighter to make it work so you're inhaling butane and probably burning more plant matter than you would in a Volcano. To each his own, though. I wouldn't mind trying the Vaporstar.
Nah mate the butane is already burnt by the time it's hitting the vape, have a look at this Rock Sci LLC - The Butane Taste Fallacy, and there is no plant matter burnt at all in the Vaporstar if you follow the instructions.
