I'm on a couple Adirondack hiking forums, and have a BearVault, so I've paid attention to those reports!
Bear Vault modified the design with a second tab because of Yellow yellow. Yellow yellow couldn't open those newer models. My understanding was that you are required to use the newer two tab models there. That is what I was told when I backpacked there.
