For all of you that like data, I've tallied this whole thread, and here are all the discs with more than 1 vote for max distance air shots:
Destroyer 14
Tern 13
DDx 9
Boss 7
Wraith 6
Katana 6
King 5
Octane 3
Northman 3
Vulcan 3
Nuke 3
Valkyrie 3
Renegade 2
Crank 2
Bolt 2
Lace 2
Daedalus 2
I didn't tally discs that people said they would throw for rollers. If you said "I might throw this or this" then I tallied both discs. If you said "I might throw this, but this other disc would be better" then I only tallied the "better" disc.
Looks like Destroyers and Terns are the distance kings for DGCR folks. The DDx made a surprisingly strong showing for such a new mold. For Trilogy throwers, the King is the distance disc of choice, and for Gyro folks it's the Octane. We don't have enough Prodigy/Vibram/Discraft folks for there to be much separation between particular molds (or many votes at all).
