I own the GuraGear 22L and the Mindshift Backlight 36L. The GuraGear is a fantastic pack for protecting your equipment. Well made, heavy straps, thick padding, heavy duty zippers and the vertical split feels natural and helps the bag hold its shape. However, for me it gets uncomfortable really quick on a hike. I think the bag is too short for my torso. I needed something bigger and wanted additional storage for clothing layers. I settled on the Mindshift 36L. It is comfortable to carry and does everything as advertised, but it is not built as well as the GuraGear. Straps are lighter, zippers feel lighter, padding is lighter, dividers are not as universal, not as many small misc pockets for the small stuff. I thought I wanted the 'load from the back' concept to spin it around and get access to my gear, but in real time with a 20+lb backpack, spinning it around and dropping it out horizontal is not as nice as it appears. I would take a closer look at the larger GuraGear if I was to do it again. PS: I carry everything you mentioned plus a Z6ii.
