The disc itself is fine (need more time/use to determine the durability of the Swift plastic), but I agree with the earlier review -- this flies more like a Destroyer rather than an understable driver as expected from the flight numbers and description. That sort of consistent overstable flight pattern is useful, of course, and if I thrown on the right anhyzer, I get a pretty good long-S flight. I got two of these when they were on sale, specifically thinking to give at least one to my nephew so he wouldn't be wanting to use one of my own understable drivers all the time; however, I've found that this is more like a -1 Turn and 3 Fade rather than the listed -3 & 1. So now I have two for myself because it's way too overstable for my nephew. 

I found this disc to be much more stable than the flight numbers suggested. I have a 154g Swift Rong that is still pretty new. 
 

When thrown with sufficient power this disc flies like a Destoryer or Nuke. A good amount of fade with a slight turn for most of the flight. 
 

Despite its weight this disc is very resistant to torque, and works well both backhand and sidearm. 
 

While this disc is not the understable distance driver I was looking for, it really is a good disc. In the hand the rim feels good without too much depth.
