Routes as boulder in Kabardino-Balkaria

I gave 8C+\9A for social media but I feel it harder than all 8C+ I tried before. I know your skepticism and understand it. I am also worried and a little afraid to state such a grade, I thought long before posting. but again, I tried a lot of hard stuff in the world and I have quite a lot of experience. I hope that I gave an adequate assessment, but I am also ready to accept mistakes in case I was wrong. Blackflip is one of the hardest 8C in the world in my opinion + 5 moves from sit. My hardest FA, my hardest boulder.
