I have no doubt that Kifaru is top shelf when taking everything into consideration. That being said, I was faced with a similar choice a few years ago and since I only chase elk every 2-3 years, and that is my only mountain hunting for now, I went with the Kuiu Ultra 6000. Half the cost, extremely light, comfortable at very high weight and room to spare on a 7 day, pack-in hunt. This year we'll be hunting for 11-12 days and it will hold everything I need. It also cinches way down and I use it for a day pack. I have been extremely pleased so far. Good luck!
