Vals (GR) or Medji (VS) for Some Gneiss Cracks? (lame pun intended)

Continuing my hunt for crack climbing in Switzerland, I'd like to check out vals/zervreilahorn or the medji klettergarten. I managed to find some short but perfect hand + finger cracks in the oberalppass area last weekend, now I'm hoping to find some longer lines.

Sunday + Monday should have great weather for it. Ping me if you're available, or also if you're generally interested in practicing some crack climbing with me.
