1) you might find climbing easier with rope paid out instead of over shoulder
2) saves untying, coiling, uncoiling and retying between harder pitches
3) can brag about how you set a new human-dog speed record by simuling Thermogenesis with your mutt
I heard some bullshit story about a party of 3 simulclimbing and one of the seconds fell and knocked the other second off, and the burly leader held them all just by crimping... and through rope drag.
