What are the minimum specs that would go for an oversized yoyo? I’m looking at the AC2 and wondering if that would be floaty any oversized

I would say the AC2 is fullsized, where’s something like the Horizon is oversized. Probably 57 mm in diameter and upwards is oversized. Ish.

50-60 is what I consider full size (I know that’s pretty broad) And any over or under is under or oversized.
Weight, and the distribution of it, (for the yoyo’s size) makes the biggest difference for me.
