I have this bag and use it with a Sigma 150-600 attached to my camera. There is still room for extra lenses/flash. I'm not sure what/how much extra equipment you want to carry, but you'd be surprised how much the front "organizing pocket" can hold. The pocket goes the full length of the bag. I've used it to carry a 580II and 430 flashes and accessories before, but usually I load it up with notebook, pen, any smaller accessories like filters and batteries and a lot of snacks. You can fit a light sweater or jacket in the front pocket if you don't overstuffed it with other things. (I've done this by carrying some snacks in one of the side mesh holders instead.) If carrying a heavy sweater or thicker coat, I have to roll it and attach to the top or sides with the built in straps.
Thanks for your input!
anything you do not like about it?
