I dunno. From this picture, almost looks thicker than 8mm? I'm comparing the width of the rope to the width of his thumb...Quote:

I think an autoblock, properly deployed, can be pretty useful.

One of my main climbing partners (see above) uses one all the time. He can stop and start on a rappel on a dime, with no effort. Of course, its usually on double ropes...
Couple of comments...I can't imagine dropping into Englestead on a single 8mm rope, on a single ATC, and not rigging for additional friction. The very idear is frightening. Glove or not (I didn't use a glove on that or any of the times I've done Heaps). Two ATCs, one above the other: smooth as silk.
Knot in the rope? I can't imagine deploying rope for a long rappel like that and having a knot in the rope. Should be carefully lowering the rope, or, using a rope bag? Yikes. It can be pretty darn scary to stop on a super steep rappel to untangle a rope...
Ain't no miracle. Had enough friction from the ATC on the rope to slow him down enough, but, that video is painful to watch.
Take care out there you canyoneering rappellers!
