If it were me... FE2, no question.

I'm not the most gentle with my gear and my FE2 has never given me a reason to doubt it ability to take the knocks and bumps I put it through. Greater durability is nice and all, but if I don't need to pay for it with increased bulk, I see no reason to. The FE2 is a good size for me; solid in the hand, but not a chore to carry.

While I don't use a flash too often on my FE2, being stuck at 1/80th sync would make me gnaw my arm off. Sync speed that slow basically traps you at a "well, at least the flash works" level. Virtually no upward flexibility, especially if you ever want to do daylight fill.
