You might have to wait a while. I looked into Condors not too long ago and as you discovered, there was not much discussion about them, here or other places. FWIW, those that did have them generally liked them. Someone must be using them or they would have been discontinued by now.
I ran into a too-good-to-pass-up deal on a Baby Condor, so I bought it. Haven't really used it yet, so I'm not much help either. It turned out just a little bigger than I need right now, so I'm just holding on to it. I like the construction, typical Maxpedition, and overall design. Feels comfortable when loaded. The fact that is doesn't have a full flat panel opening is fine with me, as I mostly use my bag in the woods and go into it often during the day for this or that as I move around. Full panels (think Pygmy Falcon) open all the way, but always seem to
want to open all the way, especially when the front pouch is loaded heavy. That's a pain when I'm standing and don't want everything to dump if I get a little careless when I'm digging around. In camp it's not an issue. As a daypack or over-nighter, it should shine. 3 days might be stretching it a bit unless you're a frugal packer. I think I could do it OK, but probably not in colder weather.
This place has the most the info about them from users that I can think of. You'll have to register to search though:
