SS - For your info this is what I take with me whenever I head off for a photo shoot overseas somewhere.
2 x Canon EOS1V Bodies
1 x 18-35 2.8L Series Canon Lens
1 x 28-70 2.8L Series Canon Lens
1 x 70-200 2.8L Series Canon Lens
Canon 540EZ Flash Unit
1 x 35-350 Canon L Series Lens
4 Packs of Batteries
At Least 20 rolls of Velvia 50 or 100
Also have a 100-300 Canon Pro Image Stablised Lens but dont like it.
All carried in a pilots helmet bag. They are great because they have pockets on the inside and outside which makes things much easier.
Have always used Canon because in my opinion with Nikon you are paying more for the name than anything else, and in fact the focusing system on the Canon EOS system is much faster.
Hope this info helps.

Autorotate.
P.S. Had a great photoshoot yesterday here in Auckland with 2 x EC130s in formation with a BK117 tagged on the end for some of it.
