I field tested the Aqu together with its siblings the Virgo, Eden & Dawn, and several other discs with 5 or 4 ratings in Speed and/or Glide, and with what I thought would be reasonably close Turn/Fade numbers; however, I found that the Aqu and Virgo were virtually reversed in stability versus their listed numbers: The 0/2 Turn/Fade Virgo always had noticeably more Turn than other discs with a -1 Turn, and didn't tend to fade back as much as others with a 1 or 2 Fade; conversely, the -2/0 Turn/Fade Aqu consistently ended up flying/fading further left (RHBH) than the rest of the stable-to-understable mids I was using. (Well, it often tied with the Scavenger, but somehow I always ended up popping the Scavenger up higher than the rest, so it had farther to come back down during its fade, letting it finally catch up to the Aqu.) Even into the headwind, I didn't notice evidence of Turn with the Aqu like I did with the other discs. It wasn't as overstable as my 5/5/0/2 discs from other brands, though.

The Aqu feels good in the hand, releases cleanly for me, and produces a great overall flight. Even though it doesn't quite match the listed numbers, I know that now and it doesn't matter to me since it flies very well. It's really a great midrange disc. Also, I like the look and feel of the Mars plastic. I just got my first few discs in this grade and only just started field testing them, so I can't say yet how durable it may prove to be. I have found so far that each of these Mars-plastic discs has a bit of flashing on the underside of the inner rim, but it's not too bad and you can find segments without it, too, if concerned about the feel and release. I think players of every skill level would find it pretty easy to use effectively, though a beginner might favor a mid that's a bit understable.
