1/2" Minimum Rope Requirements??

You will notice he has a small rope there to catch him when that 2" manilla one breaks.

If it was black, it’d just like the departure rope from a Blackhawk that hasn’t landed!

How is a larger diameter rope safer? (If a smaller rope is adequately strong,....

Compatibility to mechanical devices. Elongation under working load. Elongation under overload. Fit and feel in climber‘s hand.. Design and purpose. Being able to differentiate between lines by feel.

Many more than strength and abrasion already discussed

Modern rope takes care of pretty much all the elongation issues, fit and feel is largely going to be preference. I use the camp giant when I'm gaffing most of the time it's my safest device for sure the other being a RRP, the camp giant maxes out on rope size at 11.5mm my rrp minimum size is 11 I had one 11mm rope that flattened out a little too much for a rapid stop when coming down quickly but I milked like 3 ft of the sheathing off and it's been perfect since. Being at the very bottom of your devices rope size does require a little more attention when the rope is new untested but outside of that I haven't had any issues.

Elongation is non-linear i.e. not constant vs load according to NE Ropes tachyon but they only show an unscaled graph and no numbers. The soup thickens.
