this is a good option, very fast distros
I'm currently running Manjaro Openbox-Lite and I love it. Comes with minimal apps but the base system is very nice. Also have #! Waldorf (Wheezy) but I don;t like it as much as Statler. Waldorf feels slow and bloated. Other thing is I love Arch and Manjaro fits that bill nicely and a bit more stable but you end up with 'slightly' older packages. Anyway it runs like a demon on my old laptop.
Busy downloading Kali Linux now to test out, think it would a nice to have on a usb stick.
