It just wastes space, makes packing hard and costs money. Besides you want the bear to spend his time on the canister and not the packet of M and M's you inadvertently left in your shirt pocket. Do not hang your canister. The only known way a canister fails is to be dropped from a great height. If this is not possible block all routes of rolling with logs branches.
Bushes are great.
Nothing rolls in them. Toss it in the briar patch. Paint part of it pink or dayglow orange. So you can find it after the bear moves it. Keep it closed and locked ALL the time.
