Being me, I would go for both #1 and#2, on the basis that, given the situation of the moment, it depends.
This said, I give +100 to Roger for being so enviably minimalist, in equipment and wording...
Why clutter up a travel experience with equipment?
KISS, keeping it simple is, to me, the only way to go.
In theory, I would carry my Nikon D700 (for color) and a Nikkormat FT2 or B&W "art" shots) with three Nikon D lenses - 20, 60 and 85 or 180, the latter depending on how long a lens I need on the road.
In practice, the last time I did this, I took the two cameras, a 28 and the 85. Used the 28 almost exclusively and it did everything I wanted, almost. The 85 saw action one or two times and stayed mostly in the safe in my hotel room.
Next time, I'll leave the 85 at home and take a 60 micro. If I could afford it, I would copy Roger and take a Leica.
In 1985 I traveled across Indonesia with two Nikkormats and four Nikkor primes, a Rolleiflex TLR, and a 6x9 Linhof with three lenses and two film backs. Also a Linhof tripod and half a ton of films. Am amazed I survived the trip, but I was younger and fitter (and stupider) back then.
If anyone cares, the Rollei outshot the Linhof and the Nikkormat produced some truly beautiful Kodachromes which still occasionally sell as stock.
After that trip I sold the Linhof kit and the tripod. I now use an old Leitz tabletop which suits me fine without giving me back pains every time I take it out.
Small is the way. Especially when it's branded Nikon or Leitz.
