Look at the top of your screen. The banner is "Backpacking Light: Pack Less. Be More." Obviously, we all interpret that different ways.
For me, I interpret BPL as a place where, philosophically, people are seeking to find the lightest systems to meet their needs. If a Dana Designs packs is the lightest piece of gear that meets to OP's needs, then I hope he finds one (or three).
I don't think anyone here was trying to be rude (giving the benefit of the doubt). I trust that if the OP has done enough research, he knows what he is looking for, but seeing that he is not a paying BPL member (therefore, doesn't get to read the in-depth articles), and he's only got 4 posts on this site, I can totally understand people trying to be helpful and offer other options.
If he has looked at all the other options, he can ignore those suggestions, knowing that they were intended to be helpful -- no harm done. If he hasn't looked at all the other options, I'm sure he appreciates the insights.
I'm grateful, and I trust the incredible knowledge base that exists in the members here. However, I also know that if I come to BPL, I am certain to get info based in the bias that is what brought this community together -- a desire to go lighter. If you post here, you should know what to expect (or you will learn quickly).
If I want a liberal perspective on current events, I don't turn on Fox news; if I want a vegetarian meal, I don't go to McDonalds; if I want to have a quiet conversation with a friend, I don't go to a club blaring techno. When you come to BPL, it comes with its own expectations, and I don't think its wrong for those opinions to be shared, it's part of the health of this community.
