I have a kgo, lavatube, and just ordered the Provari. I plan on getting a Darwin as well. Back ups of course. I like the kgo for shopping trips with the wife to walmart and the mall etc because it fits great in my pocket. The LT will be in the closet for an emergency kit ha so to say. I plan on getting a nifty 3.7 or like a 4.2 box mod to replace the kgo for shopping trips. I want to get a wood bottom feeder mod for their beauty and function. Does the buying ever stop guys? LoL I'm far from rich.
