Here is what Discmania has to say about the Doombird 4:
 
The Last Flight. As our beloved Crush Boy departs, we want to make one last celebration to our 10 years of fond memories together.
These beautiful Horizon FD3s were made before Simon’s decision to leave.
Both Simon and us want to make this last flight together.
As a special send off for the Wunderkind, we are dropping the first ever Horizon Signature Series release to Discmania fans around the world in the form of the Doom Bird 4.
 
Here is what Discmania has to say about the FD3:
 
The FD3 is our true workhorse fairway driver.
Featuring a low profile, blunt nose, and concave inner rim, this disc features just the right amount of overstability to get things done.
It can be trusted to handle high amounts of wind, forehand shots, thumber/tomahawk, and snappy backhand throws from even the strongest arms.
Every player needs one of these in the bag for its sheer reliability and durability.
