I don't have the time to look now, but I specifically remember one instance about a year back where exactly this happened and both climbers ended up dead.
Oh and just a FYI, F2 falls etc do not work the same way for PAS's as they do rope falls. I'll have to look for the source when I have time, but it's something along the lines of a 2 foot PAS fall will put more force on an anchor than any rope fall. I could be wrong on that last one but I think that's what the numbers said. Wouldn't surpise me though. There is very little give in a PAS compared to a dynamic climbing rope.
So anyhow, with your system, you don't have the pro equalised? Or am I just reading it wrong. Why not just equalise your system and tie into that master point with your rope?
F2 most do certainly work in a similar way to roped falls. Its basically the same except with a stiffer spring. A large F2 onto static cord like a PAS could easily generate 30+kN ie stuff would break including the climber. Fortunately for smaller F2 falls body, harness and anchor stretch all plays a role in reducing the force.
Still if your not careful and manage to fall on static cord you are in trouble.
That said I sometimes use static slings as a safety. Though my usual approach is a clove hitch on my climbing rope.
While you are explaining maybe you can explain why you feel compelled to weigh in on every muthafuggin gear thread and carry on discussions like you actually know from personal experience? The whole rap from a sport anchor thing really illustrated the shortcomings of your book and interdweeb grad school. Now you're lecturing about static anchor systems like a freakin expert...
Splain that...? Where do you get off with the lectures there Professor?
