Very simple but versatile descender

I have discovered a few years ago ATC Black Diamond, the by-bottom-up backup device became my Lieblingsabseil- and. The rope is not crane gelt so as HMS or descender. But what one can not therefore is to secure from the top down.
The Reverso is quite simple. No, I would therefore not secure two climbers simultaneously from above, because I do not zutraue me. But otherwise it's great.
We had recently a heavy, bulky counter Stan in the fifth floor of a home draw and only had a Petzl Pro Traxion (roll with self-locking) and a simple Petzlrolle and no Reverso.

The Reverso can now be combined with the super role, and so can the Pro Traxion simulate because the role friction reduced dramatically and the rope holding the curry clamp-type clamping system of Reverso safely A fading train on the rope.

I like the combination of an ATC with two eyes, one of which is upper carabiner capable and therefore there is now by many manufacturers. I imagine that Petzl invented the system, and therefore I have the Reverso bought. Looking forward, soon time to use the thing while climbing.
