OK folks, now that I'm back in town, I can post a pic of the difference between the 2 ESP Cyclones. This is really interesting, because it seems to defy the basic rules of stability and disc shape that we have mostly come to embrace on this board...
-The green one on the left is a new domey type I procured through discspeed, and the orange one on the right is my older broken-in Cyclone.
-The under side of the rims and flight plates are exactly the same: from the bottom, there is no difference at all between them.
-The parting line heights (PLH) are exactly the same. There is no correlation between PLH and domey-ness between these two discs.
-The top of the flight plates are completely different, the green one with a large dome and wide shoulders, while the orange is much flatter and has significantly more narrow shoulders.
-In flight, the orange one has a ton of LSS and moderate HSS. Great for working all sorts of lines, even flexing out of steep anhyzers.
-In flight, the green one has almost no LSS at all and is very easy to flip over at low (150'-200') power. Like a cross between a Stalker and a Comet.
-OAT can be applied in a controllable way to flip the orange one, and the wobble will bleed off relatively quickly in flight.
-The green one flips uncontrollably with even the slightest OAT (very Comet-like), and the wobble doesn't seem to dissipate at all. Only a very clean throw and release will work with this disc.
The best way I can summarize the way these two discs fly is to say that the orange one flies like a Teebird (good HSS, holds lines extremely well at 350' power) but with lots more fade appearing at low speeds, while the green one flies like a cross between the Stalker (in terms of speed) and a Comet (in terms of HSS/LSS).
