They have the potential to go very far, but only if you have a big arm. Inside 400' my wraiths go farther with less effort. But outside 400' my Wraiths start to get flaky whereas the Riot just keeps on truckin'. I wouldn't recommend this disc unless you can already throw 400' consistently. OTOH, I've only been throwing these in cold air--they may perform differently when it's warm. My non-expert opinion is that they keep their spin longer than other distance drivers allowing for longer glide and less fade on high power shots.
The Surges I've thrown are way flippier than the Riots I've been trying. (Then again, I haven't thrown a lot of Surges.) It's more of an Avenger style flight pattern. Actually, I would say that the Riot has slightly more high speed stability than an Avenger with better speed and slightly less fade at the end. The glide seems to be pretty good--but, honestly, I'm not sure that I've ever actually gotten one up to speed.
The Riot seems to be a good choice for people who have trouble with their Surges flipping over when going for max distance. They are certainly more trustworthy into the wind. They are not as fast or overstable as a Force or an Xcalibur, but are more disc than a Surge or Wraith.
That's my experience, anyway. Take it for what it's worth. : )
I just purchased the Latitude 64 Vision @ 172g. It is an understable driver that seems to be working well for me..right out of the box. I looked at the specs. of the Riot, but went with the Vision instead. I am a lefthand backhand chucker. Hope this helps.
If I had to compare it I'd say between a Tee Rex and a Wraith in stability. Great plastic as all the Opto line discs are. The Tilted inner rim takes a bit to get used to, but I really do like the disc.
My Riots are starting to break in a bit, and I'm having a little trouble with them into the wind. (They tend to balloon on me.) It may just be my inconsistent arm, though. I am, however seeing significant glide on my tailwind shots--they keep their altitude really well.
