Like the old "choose your own adventure" books, each climb we make presents many choices, big and small. Let's look at two different transitions, moving from climbing to rappelling in a team of two, to see how our choices impact the various risks we can both avoid and bring into play by those choices.

Counterbalanced simul-rappelling is something expert climbers will do in unusual circumstances, and this gives the impression of relative safety. But in nominal climbing circumstances, what benefit are we really gaining? We break down the time-savings benefits so that we can weigh the costs.
