Kotuku (midrange). the Kotuku is valued by the Māori for its elegant white feathers, and has long legs and a long, thin neck, “which has a distinct kink when flying.” As a solidly over-stable midrange, that describes the Kotuku disc perfectly.  Like the Piwak, it is a fast midrange and perfect for a hyzer approach when you don’t want to risk running long. It’s stability also makes it a useful forehand approach disc. I never have a question as to what line this disc will take, or where it will land.
