I liked the discs. With the two that i had the lower weight one (174) was noticably more stable that the higher weight (177), and if Discraft could flatten the flight plate a little i think the disc would be a home run on their part.

2008 Ace Race Disc Approved For Tournament Play
The 2008 Ace Race prototype disc has now been approved for PDGA tournament play, which will be good news for the thousands of disc golfers who are already carrying it in their bags.
A slightly overstable midrange that fits into the Discraft line-up between the Buzzz and Wasp, the disc is scheduled for general release to the public in the Spring of 2009, when it will be renamed 'Nebula'. All Ace Race copies are now legal.
