For short trips I would leave a lot of that stuff behind.
For long trips I would leave a lot of that stuff behind.
In a large group, I would probably bring it all, but spread it out among hikers. There would be a greater chance that someone in the group might need a repair item etc and spreading out the weight would help keep packs light.
For a group, I would include some bailing wire and an awl for boot repair. (If boots are used).
For a proper bear hang, you should have more than 50 ft of cord. I bring two 65' pieces of ultralight cord for the counterbalance with retrieval cord method. 50' is okay if all you are trying to do is avoid a ticket from the ranger. If you are really interested in keeping food from bears it take more work and gear. Canisters are a huge time saver.
A sump screen to keep food debris away from critters.
A firearm in grizzly country along with the bear spray if you have an attack in wind or inside a tent.
