Fairway Driver · Both Overstable
The Innova Teebird (7/5/0/+2) and Innova Teebird3 (8/4/0/+2) are both fairway drivers, and they fly similarly, with only minor differences.
The Teebird3 is the faster disc (speed 8 vs 7), needing a touch more arm speed, while the Teebird comes up to speed at a lower power level. Both discs share the same stability rating, so they finish their flights very similarly. Estimated maximum distance is about 97 m for the Teebird versus 98 m for the Teebird3.
The two fly alike in shape, so it comes down to speed: pick the faster Teebird3 if you have the arm to drive it, or the Teebird for an easier, lower-power flight.
