Ok, let's analyze this argument. Sentence one is a straw man. Where did I say I'm picking a pack solely on weight? If I was, I would pick a cuben fiber sack at .5 oz/sq yard. The straps would be made out of cuben fiber as well. It would hold all my gear and a boned out deer for about one second before it tears to pieces. I'm not choosing a pack based entirely on weight. Do I give more significant weight to weight than most? Yes. But Some of these packs like the SG and Seek Outside packs are supposed to be more than comfortable enough, and they're capable of carrying a heavier load than I'm capable of carrying. So if the pack is comfortable, and the pack is capable of doing the job, what's the issue? Does it need to be made of such heavy fabrics that it lasts for ten years of regular hunting? Not for me. I want to go fast and light. I want to be able to cover more ground and enjoy myself more because I'm less burdened by a pack. When I first started climbing I brought a laughable amount of gear with me in a six pound pack. I couldn't keep up with my group on flat ground because they had just what they needed (read: only what they could afford, so maybe not even quite enough) and I had everything I might need and ten things I certainly wouldn't. Once we started doing third class scrambling, it got painful. I needed help to get through it. Since then I've lightened my gear by a ton, and I only take what I need. It's a joy to be able to move about in tough terrain feeling fast as I walk and light as I bound over things.
I'll also mention that sentence two is borderline another fallacy which is to appeal from authority. Having a heck of a lot of experience does not make someone correct. It means that they have experience, and they can certainly validate or invalidate more accurately than I can. However, it doesn't mean their setup is optimal. And even if it is optimal for them, that doesn't mean it's optimal for me. I have my own needs based on experience, my physique, personal tastes and style.
Anyway, apologize for the tangent, but I'm going fast and light. My pack won't fall apart, and even if it does, I'll have a patch kit, gorilla tape, and plenty of cord...
