Midrange vs Putter · Both Overstable
The Discraft Zone (4/3/0/+3) and Discraft Zone OS (4/2/1/+5) are different disc types, and they fly with some clear differences.
Both are speed 4, so neither needs more power than the other to reach its flight. The Zone OS is the more overstable of the two (stability +6 vs +3), so it fights wind and finishes harder to the left, while the Zone flies straighter or turns more. Estimated maximum distance is about 64 m for the Zone versus 58 m for the Zone OS.
Choose the Zone OS when you need to fight wind, throw forehand, or want a dependable finishing hook. Reach for the Zone when you want a straighter line, an easier turnover, or more help at a lower arm speed.
