My wife and I are heading to Thailand and Cambodia - Bangkok, Siem Reap (Angkor Wat) and Krabi - in November. Neither of us have been there before and I'm wondering what camera / lens combo to take with me. My choices are:

(a) Leica M6 TTL, 28mm Elmarit-M, 50mm 'Cron and 9cm Elmar (the Elmar is very scratchy)
(b) Nikon F2S, 35mm/f1.4, 50mm f1.8, 105mm/f2.5
(c) Nikon F5, 24mm/f2.8, 35mm/f2, 50mm/f1.4, 85mm f1.8

I'm intending to take a Zeiss Ikon Perkeo folder for MF shots and a Panasonic Lumix LX3 for some digisnaps. I will also be taking a lightweight travel tripod for low-light / temple shots.

We will be travelling fairly light but not exactly backpacking.

1. Which camera / lens set up would you recommend and
2. What film stock (colour and mono) would you take? (I usually use Tri-X 400 and Portra 160)
3. What is film supply like out there? Should I take all I'll need with me?
