I also have some 2 year old mammut slings with light fuzzing,
and some 5mm spectra cordalettes and at least as old spectra
cam slings (5mm cord) - how about those?

The Mammut cord was pulled to 4200lbs and there was some fiber
separation at the points where the biners were. Here are 2 pics:
The Mammut sling is rated to around 4800lbs.... survey
says, bomber.
The Spectra cords are featured in this short movie:

and here is a pic of the results:
The 5.5mm spectra broke at 2750lbs looped to each other. It
may not sound like a lot, but it is probably more than your spleen
can take... survey says.... kinda bomber??
They are all at a level of wear I would suspect most people would
consider 'ok' and would consider climbing on them, but it seems
that could be a fatal decision in light of recent events.
Looking at the stuff real quick style, I would use any of it
and most of it looks better than the stuff I use all the time.
I'll keep pulling the stuff and post any finds along with a final
report to this thread.
More tests: Same spectra as above. Girth hitched to each other:
Broke at 2050lbs.... your spleen might live through this.
Survey says: don't girth these if you plan on ripping onto them.
