Putter · Both Overstable
The Discraft Zone OS (4/2/1/+5) and Prodigy A1 (4/2/0/+5) are both putters, and they fly very similarly.
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 +5), so it fights wind and finishes harder to the left, while the A1 flies straighter or turns more. Both land at a similar estimated maximum distance (about 58 m).
Choose the Zone OS when you need to fight wind, throw forehand, or want a dependable finishing hook. Reach for the A1 when you want a straighter line, an easier turnover, or more help at a lower arm speed.
