After struggling with some reinstalls I figured I needed to create a basic SD image with the stuff I need without reinstalling from a scratch image all the time.
I normally need a lot of network tools, and sadly Kali turned out a bit too unstable for me (I had issues with hostapd and firmware).
Finally I figured out it would be better for me with a modified base system that could easily be reinstalled.
This image is just a raspbian image (2015-05-05)with some extra software preinstalled, and also (basically all the childish stuff) some removed.
As it is using the raspian repositories it should get all raspian updates and upgrades.
Added apps are:
