Hikers Ride Avy down Mt. Washington

With two people though isn't is hard to call whether to place running pro or not? ...

You're right, for simul climbing with running pro you have to trust that most times your partner isn't going to fall during those sections without pro.
I probably wouldn't have done any of those things on a spring day like that so I would've probably have slid too (although probably on skis). I figured I'd just mention things that could've been done if wanting to really minimize risk.
There is no one answer, their situation was unique and they were very lucky.

Thanks for posting link to these photos, as until now I thought both were wearing helmets, which I had assumed saved their lives. But, does not appear that they were, so all the more amazing that they survived. Hope that they bought some lottery tickets on their way home. Good humble attitude in their comments and captions on photos, I think.
