Unmarked passes

Hi there.
Planning a hike in mweni in sep. Looking for some different passes, not fangs, ifidi, mweni etc.
My map doesn't show trails for some of the passes, but I see comments about them being possible to climb.
Madona pass, maxome and nquza.
Are these all good to climb?
How do they rate in difficulty?
Any others in the area?
Not sure if my map is a bit dated
Thanx

Thanks guys. Appreciate it
