The rap is 140 feet.
Kinda crazy the comments here.
Somehow, I HOPE, with Heaps on your agenda, that you have the skill to descend a 140' drop using a 300' rope without risk (beyond the ordinary).
That said, it is possible to get the rope stuck on that penultimate rappel, and thus not the best idea to use your 300' rope, your tool needed to get to the ground, on that rappel. I usually bring a 150' rope through Heaps to use on this rappel, and use as a working rope in the canyon; allowing the 300'er to be used on the 2nd rappel and the last rappel only.
The Bird Perch is big enough for 4 people, though a bit tight.
