The Innova Boss was the first speed 13 driver on the market. It is one of the more popular ultra high speed drivers, and is available in all of Innova's most popular plastics. The world distance record is currently held by David Wiggins Jr. with an R-Pro Boss! FYI – Most of the plastics the Boss is made in, are stamped as a 13/5/-1/3 flight rating. However the champion plastic ones normally fly more overstable, so in many cases the champion will be stamped as a 13/5/0/03 flight rating. Innova Pro Line uses a special blend of plastics that provide unique qualities for each disc model. The different blends of Pro Line plastic produce discss with a wide range of rigidity from extremely soft to firm and stiff. 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.
