I already do the vest and the cargo pants. I carry two cameras in the pockets, memory cards, all the stuff you need for cameras today. I also go with the back pack and the biggest pelican that they will allow for my personal item. My checked bag is my "Beast" with lights and extra batteries and chargers. 68 to 70lbs. My dive bag from 50lbs to 70lbs depending on airline. If traveling with a group I will bring a third bag if someone is short a bag. It is a logistical nightmare and I sweet it on every trip. Until I have arrived and then until I am home. A photographers life is full of stress. But we bring back the pictures and stories that sell the tickets. So how about a little slack?
