Italia finally......

Years reading dpreview threads of those blessed to travel over the pond and now finally within 2 weeks I'll be visiting the land of my heritage. With that comes my decision to Tote the gear (within practicality). Here's my lineup;

D700 w/28-300
Canon 60D w/Canon 70-200 f4 and Sigma 17-50 2.8
I have a 24 -70 for the D700 but There's no way in hell
I'm going to chance walking around with that.
Some may comment why bring 2 cameras? With my luck, one
Camera quits.

I'll be touring with the above in a Crumpler MDH 7.
I'll be storing the above (with accessories) in a Domke F7
The weight is somewhat significant but not unmanageable.
Input welcome (unflamed please).
