In the time it takes to get help, your stuck person may go from a slightly injured person to one who is severely medically compromised. If nothing else, get someone to teach you how to do a 2 rope pick-off and make sure you've got a 2nd rope ready to go.

Why do you believe that?

I've started doing research into self-locking descender devices like the Petzl Stop or GriGri but I wanted to get feedback from experienced users.
The idea would be to stop an uncontrolled descent if one lost the free end of the rope or was even knocked out.
We use PMI 11mm pit rope which is fairly stiff. I know that can be an issue with some devices. The rope also tends to get dirty rather fast with fine dry dust.

Believing it is impossible to overcome is safe. Believing that by being experienced and comfortable using a single-stop descender, you have overcome the grab reaction, introduces risk of death. It seems to me that the burden of proof should be on those who would introduce risk of death. So I ask you--do you have any hard evidence that experienced users of autostop descenders reliably and quickly release the handle when entering into an uncontrolled slide down the rope?
you don't hear about people working the Stop wrong and falling often either.
