NEO is Discmania’s premium plastic for the Evolution moulds, made by Latitude 64 on a blend of Opto and Gold Line. Semi-translucent, durable, with more grip than a pure clear blend.
That puts it between the two classes it’s made from. It holds flight like a premium clear plastic and keeps a bit more hand than C-Line does. Eight Evolution moulds are listed in it.
It’s still on the stiff side in cold weather. If you want the Evolution shapes in a softer blend, EXO is the only other option on this site.
