So I Need a Bigger Backpack...

My Flipside 300 just isn't big enough for my gear anymore. In September I plan to add a gripped 7D to my kit and I just won't have the room to fit it in. What would be a good backpack to fit my existing stuff and a gripped 7D?

The Flipside 400 looks like it might be a possibility but I'm not even sure it is big enough. I like the flipside design a lot. I would like to keep it under 200 dollars too. It needs to fit the 300mm + 1.4x attached to a gripped camera body as well. My flipside 300 just barely fits the combo.

Thanks for any help anyone can provide!

Can't you just compare the WDH of your gear with the inner WDH of the 400?
