I climbed all 3 today and I don't climb much in the 5.11 grade. I thought that the Red route [Rumplemintz] was the hardest at 5.10c/d and still has some friable edges. I concur with the Yellow route [Brennivin] 5.10b/c rating. I thought that the Green route [Brennivin variation] was 5.10a, and tremedously fun on great rock. All 3 pitches are well protected. (Disclaimer: I'm 5'8" and my partner is maybe 5'3" and she led the green route.) Go do them!
