Finally........ I've finally found what I've been looking for for quite some time. A reasonably processed photo backpack with plenty of space. This photo backpack is simply awesome. Workmanship, wearing comfort, space simply great.
I now have 2 DSLRs, both with battery grips (one Canon 7d and one Canon 50D), a 2.8mm 70-200mm, a 18-135mm, a 1.8mm 50mm, a Canon 2x extender stowed away. The lenses all come with the lens hood attached, so here I save myself the endless on and off.
Additionally my cpl. Accessories such as mini tripod, memory cards, wireless remote trigger, spare batteries, bellows, etc... And I still have room.
The burner is also the fanny pack, which can be clicked on the backpack if necessary. This sits on a nice wide waist belt and is fixed in the middle with Velcro so that it doesn't slip back and forth. I find it very well thought out. I still attached my monopod to the side. I prefer to take my tripod in my hand when I need it, otherwise it would be too heavy for me with the gimbal head back there.
I will probably use the fanny pack to take small bottles and a small snack with me. Saves dropping off the backpack when roaming the area. Everything perfect so... I'm definitely happy and I can only recommend this part.
