Thanks very much! It is really an amazing shooting gallery out there... so much to choose from. I forgot to mention my experience with carry-on baggage. One of the things I was most worried about was how I was going to get all my equipment on board, without having to check anything fragile. I used a Think Tank "Airport Addicted 2.0" bag, which is the largest legal carry-on bag you can buy. It has backpack straps rather than wheels, to maximize internal space. It was way overweight (35 pounds) and I was ready to pull out a couple items if I had to. But it never got weighed, on any of the 6 flights we did. I just made sure to line up in front when the plane was boarding, to ensure I could find space to put the bag overhead. After that it was not a problem at all.
