I cracked my brake chain a couple of days ago, zip lining the echo for refuel, it hit the ground hard and cracked a section of the brake bar, making a bit difficult to unlock. Need to replace soon.
Not my finest hour.
Non the less.
If your life line is not set, and you get an injury, how are you going to bail? What about a wasp or bee nest. Get stung to shit while setting your line to bail.
Also, gaff out, and those little stubs impale you. No stubs. Hell on rope too.
