Today I had a look at the harder version called "Meiose" and I have to say, the way Pirmin Bertle climbed it, it is 9a+. That's not the way it makes sense to me though as it eliminates some holds that are totally in reach and in the line too. I did climb route (in my eyes) and clipped the same line of quickdraws, but I used very different beta and also different holds for some parts. I just did it the way it seemed logical to me. The way I did it was around 9a, but it has nothing to do with the original beta Pirmin used. [1]
