ive had both
AO is a pearl even tho it was sanded it still hated carry down
Big Curve stronger midlane read, for me the BC was better at 1k abralon with some polish, this way it retained a bit for the backend
both balls in my opinion were rolly with midlane, I was easily able to use both on med conditons as I liked both better polished
