I believe the saying goes something like "if I throw a dog a bone, I don't want to hear how it tastes." You came here asking for perspectives and got a few different ones from people with experience you lack, some in a polite-direct fashion, some with a bit less flower in the prose. FarmerJ has served in the armed forces and likely has experience humping a pack and combat gear in the field so you may want to swallow pride and consider his perspective even if you don't like the way it was presented.
I disagree. I did come in here asking for opinions. However, I do expect people to respond in a mature fashion as I did initially. Had Farmerj presented his ideas like someone actually trying to help, instead of sarcastically trying to boost his ego, I would have been significantly more receptive. It's not tough to be mature about your responses. The internet doesn't give a license to be a jerk, despite the fact that a lot of people seem to believe it does. (Granted, it's almost impossible to govern the internet in such a way.)
You don't even fully know if he HAS experience humping a pack. As you said, "likely". He didn't even mention his experience in his responses. Regardless, I did ask my military friend about some of the stuff that farmerj mentioned. (That's a benefit I have. I can legitimately validate stuff being said.) Farmerj did post a couple concepts worthy of validation. So, swallow my pride? No. Will I let someone get away with being a jerk to me? No. Will I validate what people say regardless of they are jerks or not? Sure.
