As most of the guys stated above both the MR and the Kifaru are excellent packs, I don't know as much about the Kifaru as the only experience I have with them is through my hunting partner and he loves his I believe its a timberline, with over 5 years on it I believe. I've worked with MR for a number of years in the fire world and last year ponied up and bought a CC for myself, I'm 6'1" and the large yoke works great for me load lifters and all and my torso is in the 21" range. It is worth it with the CC to get at least one load cell to help organize small stuff since there is less fully enclose cargo area than the longbow or other nice frame based packs, but you should have no problem putting more weight in it than is humanly possible to carry for a 5 day hunt. The other nice feature of the NICE frame is that it is possible to swap the pack on it if for a somewhat reasonable price instead of buying a whole new system.
