I've been using my Destroyers for a little over 2 months now. I had given up on Wraiths and TeeRexes (and I didn't find the TeeRex-X to be that stable...) and was using Avengers for distance. (Max with X Avengers was probably 410-420, 380-390 with Z.) I found the 1st Destroyer I got (a 170 first run star stamp) to be very similar in flight to my Z Avengers, just faster and longer. It's broken in now, but even brand new, I didn't think it was that overstable. The HSS seemed pretty good, but the LSS wasn't too much to work with. I've since thrown a 175 Star which was a pig, a 172 Pro which I only threw a handful of times and wasn't a fan of, and a newish 172 Star stock stamp that is now my overstable D since the 170 is sufficiently beat in.
The thing is definitely fast. It's odd though, it doesn't seem that much faster than Wraiths or TeeRexes, but it just stays faster for so much longer. The biggest thing I've noticed, is that even when I'm off in my throw and it comes out badly, it still goes forever.
When I get it turned over, it doesn't behave very nicely though. The disc is so gyroscopic, that it just seems to want to hold the angle and I have a hard time getting it to flex back in time. So I tried throwing anhyzer for distance, and it wasn't stable enough to get a full flight. I tested against my Z Avengers, and they were way further given the height and the anhyzer angle.
Spike hyzers are sweet with these, too. I like throwing completely vertical spike hyzers, and I can get sooo much height on these babies to clear anything.
So I like it. I carry two now, my beat 170 and a new 172. For wide open distance, I'm impressed. A couple times a year you hear about the newest, fastest, longest disc and I usually find them nothing special. This thing really goes though.
