I have been following the Blake style minimalist less overstabloe disc program. I am very happy with this program, as in a short period of time I have learned that throwing long and straight is mostly about the throw aad not the disc.
I have a stack of Pro Cyclones and few D Cyclones. Their flight vary very consistently by weight. Heavier discs are mosre stable lighter, less so (the exeption being the "more overtable" POS Cyclone2 I have in X plastic that flips over faster than Paris Hilton) . The Cyclone flies generally about the same even when warped and pretty beat, and I have only thrown one away that I bought from the used bin). The disc has to be totally beat, and I mean totally beat not to fly pretty much normally.
One thing I have noticed is that the D-Cyclone is noticably slower than the old "Cyclone plastic" Cyclones, and those "Cylcone plastic" discs are slower than than my first run Cyclone. While the furst run Cyclone is noticably longer (by about 30' on average) the D Cyclone is just as long as the Pro EVEN THOUGH IT FLIES SIGNIFICANTLY SLOWER.
In an effort to find a faster, longer Cyclone, I bought 3 DX Eagles. The main concern being the rim width. I have a grip that works very well with all of my discs (Cyclone, Roc, Aviar, Cheetah) and I HATED the fact that my grip had to change once you gradualted to an Orc or Wraith. I HATE THIS!!! "Old style" discs have no wing, and mostly bead, and the rim fits into the crook of my index finger just great, so I went to the store and found a disc with a cyclone like bead tha fit my grip.
The Eagle is good disc and is very "fast", even compared to a Wraith (I think). The glide (for me) is very Wraith like, in fact. One point of fact is that DX plastic "glides", period, and there is no need for a huge wing to get the glide, like you need from CE plastic. The flight of the Eagle is very Cyclone like (small hyser flip, almost no fade) but is much less forgiving than a Cyclone. The Eagle is significantly more forgiving than a Wraith, Orc, etc. Nose angle is so critical on these discs for max D.
I have my longest field throw to date with my 172 Eagle, which was 480 feet. It was all in the glide, not the snap BTW.
Glide is everything, the disc must FLY to go far IMHO. Everyone is so enamored with speed, but the it is the glide that ALWAYS gets the big D for me. Speed is just easier to throw 350' (hence the overwhelming popularity of fast discs). After that most people need glide. Also, are people willing to throw these discs against each other in a field and truly see the difference? I doubt it, or they might be wondering why they would sacrifice pinpoint accuracy for 3-5 steps in distance (and most likely only at certain wind angles)...
...I have a buddy that can tomahawk a CE Orc 300', and it never "flies" (in the true flying disc sense) at all. I "fly" my Aviar 300'. In a real sense, maybe not as effective overall, but I do not see throwing overhand as improving any other aspect of the flying disc arsenal. In other words, try tomahawking a 150' tight tunnel shot.
Yesterday I bought two DX Teebirds. The disc appears to be a refined Eagle, and has almost ZERO fade. It appears to be even a bit more forgiving than the Eagle, but I am not will to say that yet. It actually flies like a fast Roc (although not nearly as forgiving as a Roc) and the glide is dead straight. If the wind is not blowing in excess it will go right where you point it (like a Roc), and is very long with a reasonably good snap.
This brings me to my question, if the wind is blowing what would be a good disc for headwinds, with a short wing (small bead), in DX type plastic (it does not necessarily be Innova)? Is the XS overstable enought to be a headwind disc?
