About the Innova JK Aviar-X
The Innova JK Aviar-X(Juliana Korver) Aviar is a more overstable putt & approach disc than other Aviar models. The JK Aviar is made from the same mold with a special blend of Pro-Line plastic that is more flexible and grippier. The JK Aviar has the same flight characteristics as the Innova KC Aviar. The JK Aviar's softer plastic excels in colder climates.
About Innova JK Pro Plastic
Pro plastic is more durable than DX, and provides a better grip than Champion Plastic. Discs in pro plastic tend to be slightly more understable than counterparts of the same mold in other premium plastic blends.
