Gear suggestions for Peru trip!

My wife and I leave for Peru tomorrow and I'm in the process of packing my camera equipment. Initially I had planned to take my E-P2, but now I can't (a story for another day).

So here's the gear I'm certain about:

1. E-30

2. 12-60mm lens

3. 9-18mm lens

Now, I have these on option, but not sure which to carry:

1. 50-200mm (too heavy)

2. 40-150mm (light but less reach and slow)

3. Zuiko 50mm & Sig 30mm (for portraits?)

Which of the above 4 lenses would you carry? Also, would it make sense to carry my Metz flash?

Now, my wife isn't too happy about me mulling over all this gear since it's supposed to be our honeymoon but she understands that I want to take pictures.

Also, I remember a few folks here who've been to Machu Pichu and I'd love to hear from them as well.

Thanks for all the help and suggestions!
