I think you should wait til you use the Fury before buying another vape but that's just my opinion. I'm not trying to turn you away from a Mighty, but there's gonna be a good bit of overlap between the two devices for a weekend toker with a lower tolerance.
I've puffed so many volcano bags on my patio, it works great for that. It's one of the most portable vaporizers out there as far as desktops go. How many bags does it usually take you before you are satisfied?
