I can't compare the vertigo to the AI, but I can compare it to the OI.
My vertigo(pin above ring finger, RAD just right of thumb) is actually very verstitile. I can use it on anything but dry with wrist adjustments, but even if you don't throw many revs it still hits hard where the OI doesn't. I don't know if this is the case with the AI, but with the OI it seemed to be less of a good core/ coverstock combo. I felt like the core made it want to hook early and hard, but the cover wouldn't let it. Then it gets to the backend and the core doesn't want to hook anymore. With the vertigo the core and cover seem more on the same page. Sorry I can't compare with the AI, but from what I understand the AI is sharper and a bit later than the OI.
