Would girth hitching a longer prussic into the guide loop of a tube style belay device be an acceptable backup for a rappel?

I have been struggling all day to not go outside and make that video . . . I guess when I finally gave in the YEET was pent up.

Why are there so many MP threads on alternate rap knots and rigging?  What problem is being solved?  I recognize that some of the tag line / blocker techniques might have their place but for 99.9% of climbs and descents the basic shite is really the better choice.

Ahhh got it now. When I backyard tested it last night I just grabbed an ATC and a small prusik loop that was too small to girth it after having applied a klemheist, so girthed the loop to start off but finished it off with a locker, so I was actually attached to that locker. Using a longer material just now I see that if you’re not on the brake strand then you’re gone.

Just to reiterate, I was never advocating for this method, but I was mistaken on a point of its failure. 

5 posts later, you finally understand.

YMMV....

There was also good info. That happens a bunch on here. Someone brings up...whatever....and a whole bunch of info pops out. 

And, at least the OP is thinking about stuff. Everything we do, was someone's idea at some point, eh? 

Best, H.
