Putter vs Midrange · Both Overstable
The Discraft Luna (3/3/0/+3) and Discraft Zone (4/3/0/+3) are different disc types, and they fly very similarly.
The Zone is the faster disc (speed 4 vs 3), needing a touch more arm speed, while the Luna 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 57 m for the Luna versus 64 m for the Zone.
The two fly alike in shape, so it comes down to speed: pick the faster Zone if you have the arm to drive it, or the Luna for an easier, lower-power flight.
