I was in the same situation like you! I have my z600 tc with few others lenses and two bodies and I could not find anything that fit them all. With the help of a representative at B&H, i bought the Shimoda Design Action X70. I can fit, thé Z600 tc, the z 400 mm f4.5, the z 24-70 mm f2.8 , a macro z 105 mm and two bodies, the Z9 and the Z8. if I want to fit my z 70-200 f2:8, I have to put in the upper pocket. This bag has also a lot of pockets for cloth, laptop, cell phone and other stuff. It is very confortable to carry it On the back.
I had a Video chat with B&H representative, I told him what I want to carry. He tried so many backpack with the gear i mentioned, in front of me in the video chat and the Shimoda was the only bag that fit them all.
