Destroyer FAQ's:
1. What plastics do Destroyers come in?
DX, Pro, Champion, Champion Glow (CFR), Star, and Echo Star. There are also many
more limited runs of destroyers such a Night Shift, Special Blend, AJ Star, etc. Innova loves to experiment with this mold. There are many blends of champion/star and of different star polymers out there that make them feel very different but they're typically just stamped with the production star plastic stamp.
2. What do the different markings for Star Destroyers mean (S/DS, *DS, etc.)?
There is a contested/debated theory as to whether the different markings (i.e. SDS vs *DS) have significance. Though more people believe that the differentiation is intentional, as in more than just two ways to note "star" plastic, there is not a consensus as to what the differences are or how closely they correlate to the markings. Some say it is as simple as two different people who mark the discs have different ways of noting, some believe they distinguish runs of the disc chronologically, and some believe it distinguishes runs of the disc by polymer composition.
3. What is a "Vulcan Top" aka "Destrulcan"?
Prior to the release of the TeeDevil as a separate mold, Innova molded up some Destroyers with a top/wing of one of their at-the-time new discs - the Vulcan. The Vulcan is different because the disc makes a sharp "corner" as you follow the profile from the edge to the center. Innova did not stamp these differently at first, and so you havve some destroyers that are actually what would later be made a separate mold and called TeeDevils. Innova has used this new top-piece to mold up another disc, the Archon, which utilized the vulcan top and a wraith bottom.
4. What type of Destroyer is most ____ (overstable/understable/durable/etc.)?
Another hotly debated topic. The typically accepted guidelines are as follows:
Understable ---> Overstable (by plastic)
DX | Pro | Echo Star | Star | Champion | Champion Glow
Note that there are exceptions to this order, so take as an in-general guideline only and not a guarantee.
As far as *DS vs SDS vs...it's a crapshoot. The only thing for sure is that a Vulcan-Top/Destrulcan/TeeDevil will beat in to be more understable or flippy than a regular destroyer. Some TeeDevils start more understable, but some start just as overstable/beefy as their non-vulcan-topped counterparts. There's no guarantee. Many vulcan-tops have a good bit of flashing on the edges of the rim, and I've personally noticed that removing that flashing significantly and immediately changes their flight.
There's much more/different of an answer to each question depending on who you ask, but I tried to reduce speculation in hopes that this could be a reference for people with the same question. I also invite anyone to add/change this as necessary to keep it current/correct.
