Hi I recently switched form a Lowepro Rover original to a Lowepro Flipside 400 AW as I was having difficult removing my camera and lens from the Rover when fully packed. I can still take as much stuff in the Flipside only change is that some things such as my purse now go in the main camera compartment as the outside compartment is not as wide as the top section on the Rover. It was also cheaper than my original Rover. The waist belt is not as wide as the Rover but I have been really impressed by the Flipside and just how much stuff it can swallow. I did have my doubts when I first brought it home. Also it is comfortable to wear for long periods. It will certainly take the kit you are talking about and more. Finally when placed side by side with the Rover it is the same size, possibly marginally smaller.
