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. DX is an inexpensive, basic plastic. It has good grip, but wears more easily than premium plastics.
