city photography advice

I'm heading to Barcelona in a few weeks time for work but should have a little bit of time to enjoy some photography at the weekend and evenings. However, I'm struggling to decide what gear to take with me. I was hoping that some more experienced photographers could offer some advice. Here's what I've got as options and my initial thinking on the matter. I'd like to travel light - not more than 2 lenses ideally.

bodies:
k100d and kx

current thinking:

• just take the kx, no need for 2 bodies.

lenses

• sigma 10-20

• da l 18-55

• da 50-200

• k24/2.8

-fa35/2

• m50/1.7

• m85/2

• k135/2.5

• tokina 20-35/2.8

• tokina 28-70/2.8

current thinking:

• take the sigma 10-20 ultrawide and just add one lightweight telephoto, either m50, m85 or da 50-200. Although its really hard deciding which. I was hoping that this combination would allow some nice wide shots of the city plus some close-ups of details or arty dof shots.

tripod

• velbon cheap and cheerful.

current thinking:
leave it at home and buy a gorilla pod for some lightweight flexibility

what would you take and why ?
