I agree with many smaller cards, rather than one big card, eggs/ basket etc
Also, get yourself one of the extension sticks, it lets you take selfies as well as a heap of other uses, like out the passenger side window while driving, right up close to animals, what ever you can come up with...also those small cameras get to be a pita to hold.
Have a think about getting multiple mounts that you can firmly secure onto you roof racks, sliders, bull bar, diff. Then you can just move the camera to where you want it rather than undoing/doing up the mount all the time. 10 minutes of fiddling for a 30 second "action" shot.
