CV joint is the first thing that leaps to mind. That's the sound my brother's car made just before the wheel came off in traffic while he was doing 60km/h over a bridge
As birth rates decline and lifespan lengthens, eventually there will be a point where adult diapers outsell baby diapers and are mostly worn by old people and diet drug addicts, as well as astronauts.
Then I would imagine a cute skirt is definitely out of the question.
A cute skirt and no panties (or a kilt for that matter) is just less clothes less to get shit stained. Combine it with an adult diaper for a space-age look that says "Obsessed Astronaut"
Flying Circus is a hell of a lot more polished than it was when first freed in the 70s, (or even than it was when I first climbed it in 1991) but it's still 10a. You just have to be more precise with hand and foot placements.
The key with any of these devices is to avoid dynamic falls.
The Ushba, Shunt, and MiniTraxion will cut the rope at around 6 kN. These forces can be generated by, say, clipping in to the device with a long sling instead of directly to the harness.
The Rocker was designed to be stronger and I think, will hold falls up to around 9-10kN.
That's my memory based on some data that was referenced on buildering.net, and a climbing mag review of the Rocker. I have no links archived to back it up. Research it yourself if you need more info.
Instead of a HMS pearbiner, I use a 1/2" stock maillon rapide/quicklink to attach the Ushba to my harness. I found the pearbiners tended to swing around and potentially crossload the gate. The quicklink is long and narrow so it tends to keep the Ushba at one end and doesn't crossload.
Polish is just a requirement for good technique.
Just like having bad technique doesn't let you claim a 5.6 as a 5.9, polish does not increase the grade of a route.
