Went with AO on my Fireball and on one of my .22 rifles because I can be rather deliberate with either of those. Just something else to fiddle with when I want to be more precise. The 10/22 has a 2.5-8x36 Leupold on it and that works just fine as a shoot-um-up scope. More than once I've been fiddling with that AO and the target in question left the scene.
