I have one (had it since it came out) and longevity, consistent-roll and carry are what immediately comes to mind. I don't have a full swing so I don't know how they compare/contrast, but I would say the AA is great on any med to heavy oil - just drill it for desired reaction and adjust the coverstock to fit the conditions. I wouldn't want to rely on it for broken down conditions though, as it definitely needs head oil and relatively clean backends. It would be a good middle ball if you have a pearl to go to for broken down conditions. Polished the AA gets a little squirrely, but anywhere from 1,000 to 4,000 grit surface is fine. One more thing, if you do want to use it as the lanes break down: as you move left to get more head oil, you'll have to tighten up your line to the pocket as it has a very low RG - early roll and not alot of backend recovery.
