Fairway Driver · Both Overstable
The Innova Teebird (7/5/0/+2) and Kastaplast Idog (7/5/-0.5/+2) are both fairway drivers, and they fly very similarly.
Both are speed 7, so neither needs more power than the other to reach its flight. The Teebird is the more overstable of the two (stability +2 vs +1.5), so it fights wind and finishes harder to the left, while the Idog flies straighter or turns more. Both land at a similar estimated maximum distance (about 97 m).
Choose the Teebird when you need to fight wind, throw forehand, or want a dependable finishing hook. Reach for the Idog when you want a straighter line, an easier turnover, or more help at a lower arm speed.
