First, I don't think we should confuse what we really need with what some bureaucrat requires. Some must comply with certain area rules to hike there. In that case, you must select a canister from their list, and use it, period. Ship the thing where you must have it, and ship it back out ASAP.
Some others, like moi, avoid those certain areas like the plaque. Those areas are over-used, worn out, and unattractive to someone who hikes in wilderness areas. Unless you are thru-hiking and there is no way other than to pass through them, IMO you are nuts to go there. It is no one's fault, they simply get too much traffic due to their reputations and government and other publicity.
OK, if you are thru-hiking a major trail, you often have no choice. That is why I have made it a lifetime project to locate a different route for one of the major trails in one of the most scenic and backpacker friendly States. The recent demise of the CDTA, and the Forest Service's unadmitted but persistent policy of abandoning high country trails further underscores the need for this.
For actual, functional bear protection, not related to moronic agency regulation, I have a couple suggestions:
First, the last issue of the BPL print magazine had an article about small-battery powered, electrified containers. After seeing one of the readily available little Tasers purchased by a lady friend, I was impressed. Pretty daunting. A sack or container that emits that kind of message when nudged by a bear ought to be pretty effective for practical (as distinguished from 'regulatory compliant') purposes.
Second, some of the odor proof bags, like OpSacs, have been shown to really work, so long as you are careful to not place odors on the outside of them by packing up food with traces of food on your hands. Easily replacable and more securely sealable liners made out of this material for the electric sacks would greatly diminish the likelihood of molestation by bears and others.
A light weight product with the above features is something I would definitely buy for a reasonable price (not the $300 or so mentioned in the BPL article), and for protection against wildlife, not from other humans with fancy outfits.
Will still hang bearbags for added protection, and to avoid other clever varmints. Bears have been known to make off with those 'regulatory compliant' canisters. If we really help them to avoid us, we can co-exist with them much better. That's my desire, because I really like them.
