I don't know how much the padded dividers weigh. I would guess about 3 pounds as they are pretty light weight foam padding with lightweight nylon covering. The specs on the Pelican site shows that the pluck foam weighs about 6 pounds. (the pluck foam is really not suited for underwater photogs as it disintegrates with use and wastes space). The dividers use a denser foam but much less square inches of it.
I also reused my Pelican 1650 lid divider, which helped me clear space in my carryon Tenba packpack which carries 2 dslr bodies, 3 lenses, laptop, critical chargers, iPod, diopter set, etc.
I'll be using this setup again in my future travels.
