This is in stock at my local Dick's. I will be fondling it within a few days (big blizzard rolling in today). Might be a solid new alternative. It certainly looks preety damn cool.
The fact is, the Cabela's bags are no longer being made. There will be a time when calling and hunting them down will no longer work. There's a finite supply out there, and it's getting smaller daily. The DIY crowd will either find a new "flagship" bag to promote, or it will splinter off into a half dozen regular options.
