Putter · Both Overstable
The Axiom Envy (3/3/0/+2) and Discraft Luna (3/3/0/+3) are both putters, and they fly very similarly.
Both are speed 3, so neither needs more power than the other to reach its flight. The Luna is the more overstable of the two (stability +3 vs +2), so it fights wind and finishes harder to the left, while the Envy flies straighter or turns more. Both land at a similar estimated maximum distance (about 57 m).
Choose the Luna when you need to fight wind, throw forehand, or want a dependable finishing hook. Reach for the Envy when you want a straighter line, an easier turnover, or more help at a lower arm speed.
