new techniques of rappelling

[hillrambler]

There are several reasons not to do this. Yes it doesn't twist the rope like a munter or figure 8 but you have gateload possibilities as well as no real control of friction other than your hip. Maybe good for short drops but an actual descent device is best.

Looks less likely to twist the rope than a munter, as with all rappel devices if you just look the rope behind you, you can add a ton of friction
