The carry-on limit is an issue.
Doug, I plan to use a backpack for the camera gear. While I may push and slightly exceed the 11 lb limit it usually does not look like it weighs as much as it does. Good to hear you are carrying two bodies as I was planning to do that also. I did that on ROAR 3 and it worked very well. Not so sure on the Zodiacs but it is nice not having to change lens just change camera body.
I am still uncertain about taking the small computer. Will take the I Pad for sure.
Wonder what they would say if we carryed one of the cameras with large lens around our neck. Like your idea of putting stuff in pockets. You must have a big pocket for that big lens.
Really starting to get excited about this trip.
