2) They won't necessarily catch you. They'll break, especially under your

On Yoda, a sudden lurch caught my friend off guard and he toppled from the
cabin trunk. The lines caught him, though at 6'6 and near 300lbs he certainly
tested them. There's no way a proper lifeline will break from someone's weight,
unless the core is rotted or the lines are bad. NO WAY.
