I use the lowpro lens trekker 600aw for my 600mm with the mk11n attached. I also carry my 180mm in a side pouch. I carry both 1.4x and 2x extenders in another pouch. My flash and better beamer are in the bags attached front pocket. I have a mesh water bottle holder on the waist belt. and some times my binoculars. I take either the tripod or monopod but never both. I usally have all this in the bag when I go distances but sometimes I will carry the 300mm 2.8 with the mkIIn attached and leave the 600mm in the bag so I am ready for those quick grab shots. When I get where I want I then switch lenses, I set up the 600mm and the 300mm goes in the bag. This has worked very nice for me.
