When Discraft tried to run old molds in the then-new Z plastic there were at least three notable failures that resulted in really overstable, glideless turds; The Magnet, Hawk and Cyclone. All three were good 90's discs that just did not translate to Z plastic at all. Nate Doss threw Z Hawks because they were 100% power player discs. If you didn't have a Doss-like cannon, there was no reason to bother.
ESP Cyclones were a good, workable driver. Whatever Hellish demon possessed the Z Cyclone was exercised from the ESP Cyclone.
I don't expect that the Ace Race Hawk will be in Z since Discraft already knows that they will be glideless turds. They will probably be ESP or Jawbreaker or something like that and hopefully fly closer to the workable Hawks of the 90's, which flew a lot like a Cobra. As I recall you could get one over but they had a strong fade back at the end, so S curve Cobraish kinda flight.
