The illustrated disc flight line is based on the manufacturer field testing results, during its development process. So, to level the playing field we chose to put a different spin on things for such visual illustrations. Sticking to the manufacturer's test results will offer you a good baseline for how that particular disc will fly.
The Innova JK (Juliana Korver) Aviar is made from the driver mold in a special blend of durable Pro-line Plastic that is more flexible and grippier than the other Aviar models. It has the same flight characteristics as the KC Aviar. Its softer plastic is better in colder climates and for those who have dry hands and require a tackier grip.
