Start sitting just to the right of the big face of Thrutch and Wiese and just to the left of the long low roof. Climb up the face using (you guessed it) a mono.
It is possible to continue into Thrutch and Wiese or forge your own way up the wall. Top out.
Harder that V2 in my opinion. And be careful on the top ledge, I hucked for it and grabbed a handful of gravel, spinning me sideways off the top and down to the pads, missing them with one of my feet.
