The Piwakawaka is a good, reliably straight disc. It will easily hold a line and has a good bit of glide.
Speed: 4 | Glide: 5 | Turn: 0 | Fade: 0
The Strata plastic is a performance plastic which is tacky and medium to stiff. This is a good plastic for when your discs get wet, and it breaks in nicely, especially for those favorite putt and approach discs that you want to gently rock over. This plastic is similar to Innova DX with a nice, chalky feel.
