I was once very resistant to the idea of bear canisters. I had practiced the two-rope counterbalance hang in Yosemite for 20 years of group trips with perfect results. Then one time I had signed up for another leader's Yosemite trip, and he made canisters a requirement. So, I bought a Garcia and used it. If you are not used to them at all, you will find them to be a PITA at first. Later, you just resign yourself to it and try to learn to take advantage of a canister as a chair or table. Some years later, I bought a Bear Vault, and it seemed a little better. Then later, I bought the small Bear Boxer. For a longer trip, I might carry the Bear Vault, and for a shorter trip, I might carry the Bear Boxer.
Note that the small Bear Boxer is smaller in diameter than the rest of the market. Still, it is big enough that a standard, garden-variety, Yosemite black bear can't get its mouth onto it to bite, and it can't find any holes big enough to apply teeth or claws. I don't think that this Bearier should have exterior loop holes for straps, although interior would be OK.
In Yosemite, it has gotten to the point where the bear walks into camp at midnight, sees the canister, knocks it over with one paw, then continues walking. I generally plant my canister in the middle of some big rocks so that the bear can't get any rolling started.
I'm always amazed when I see somebody putting their bear canister into a thin nylon sack so that they can hoist it up into a tree. Then they tie off the rope near ground level. Geez! That's bad. The bear finds the rope, and bites it or claws it until it fails. The sack with canister falls to the ground. The bear bites the sack and carries the whole works off for further examination.
I still advocate decoys. Hang up an empty brown paper sack with a piece of bright white cord, maybe 8 feet off the ground. It has no food in it, so the rangers can't hassle you about it. The bear spends a while fooling with it, and you get the flash photos.
