I would imagine I have a dozen posts on this pack frame and I'll gladly pitch this product again. I don't think think there is a better value on the market. One small complaint is as mentioned the squeak, but I wouldn't give it that bad. And after about 20 heavy loads, mine just about disappeared. For heavy loads, 50 plus pounds, it's flat impressive and VERY comfortable. Last year, I had to use my buddies high end pack for a boned out deer, I was excited to have the chance to compare the 2. It did not even come close. The advantage of have the heavy load up tight against your back has immense value. Then there are 2 values of this pack that no one ever mentions:
1) when you have that heavy load and you need some sort of break, you can reach underneath your frame and lift up on the bottom of the bars with your hands. This transfer 20 plus pounds to give your back a break. This year I packed out my deer 2 1/2 miles and only had to take 1 break to rest with this combo.
2) by far the biggest value of this pack on a daily basis is being able to sling your rifle over the top bar of this pack to carry the load of the rifle distributed over the frame vs. over one shoulder. This small thing is wonderful over a few days span. I'll try and find a pic to reference what I am talking about.
Love this pack and can confidently say the best pack on the market. And to address the 5,000 cu in... It's way too much. I dont use that bag I had it modified to about 3-3500. You cant have more than this if you are going into the back country on a hunt. Now days with better gear, more light weight, you just don't need a bag that big.
