I recently tried an XPro-2 and loved it so much I bought one, sold all my Nikon equipment and bought an XT-2 and some lenses. I'm traveling India for six weeks with a backpack and small camera bag. I brought both bodies, five batteries, a bunch of cards, four lenses: 16mm f/1.4, 23mm f/2, 35mm f/1.4 and the 56mm f/1.2, a travel tripod, a MacBook Pro and two hard drives.
I'm really happy with everything and how all the gear is performing. If anyone has any questions about how the gear is working out, please feel free to ask. I started a website for my trip, the Fuji images are under my blog and in the India image gallery. I'm only a couple of weeks in, but I've figured out my workflows and what setups I like. Thanks for letting me share.
