gear advice morocco (Marrakesh)

[pnewbery]

I will be going to Morocco (Marrakesh) in november I have decided to travel light and not take my Nikon D3. Ideally I want to take one camera lens.

I have leica D-lux 3 and Nikon D5000 with the following lenses

Nikkor 20mm F2.8
Nikkor 24-120 VR
Nikkor 60mm f2.8 (micro)
Nikkor 24-70mm F2.8
Nikkor 35mm(DX) F1.8

Currently I favor D5000 with the 35mm but would welcome other suggestions.(I found the d-lux 3 slow for grab shots)
