I did some reading on the "ask dave" thread to find out what the scoop is on the PD and DD, found some good info. A beat in PD sounds like it should be a nice disc. For the PD:
Dave_D wrote: The bottom looks like a Firebird or TeeBird. It flies in between these two for characteristic, but longer than both. I used the TeeBird for shots between 280 and 350 when I needed to maintain a line in a breezy situation. I think the PD has a slightly higher fade than a TeeBird, but less than a Firebird. The TeeBird has more carry and less speed than the PD. The PD is a much better side arm disc for me, so it was a no brainer to have the PD for the short drive, long approach hyzers. I use it as a TeeBird, Starfire, and Firebird.
And for the DD:
Dave_D wrote: The PD is not quite as long as the Starfire, but holds up better in winds. The PD also has more torque resistance. The PD holds the angle you throw until the fade. The fade is similar to a Starfire.
Dave_D wrote: The Distance Driver is more or less between a TeeRex and a Wraith. It has about the same high speed stability as a TeeRex, but less low speed fade, which makes it easier to hit long fairways.
