Here's my light weight rig I use while hiking. G9, super pod, and a ex580. Yes, the flash is grotesquely large, it does an excellent job fighting the Arizona sun. Using its high speed mode, I can still use fast shutter speeds and wider apertures with fill flash performance the built in can't touch.
I know I've knocked the G9 before but it's got its place. The rig is light weight and easy to carry - the folded tripod makes a good carry handle.
