I think that ar10 and od8 is fine (for Extra), however learning towards ar9.5 and od8.5 would be alright too. I feel that ar9 would be awkwardly low (i always played this map ar10, even when i wasn't good at ar10) and od9 would be really on the harder side nomod. I feel like i'm kinda in the target audience for that difficulty, and od9 is a bit much, though it would inflate PP for those that can play it.
I really don't like the slider-circle-slider with that aggressive spacing in the last kiai time though. The difficulty spike from the spacing at the end feels fun, but those circles i'm just gonna break on 50 times and be annoyed.
