Midrange · Both Overstable
The Discmania MD4 (5/4/0/+3) and MVP Disc Sports Deflector (5/3.5/0/+4) are both midranges, and they fly similarly, with only minor differences.
Both are speed 5, so neither needs more power than the other to reach its flight. The Deflector is the more overstable of the two (stability +4 vs +3), so it fights wind and finishes harder to the left, while the MD4 flies straighter or turns more. Estimated maximum distance is about 77 m for the MD4 versus 74 m for the Deflector.
Choose the Deflector when you need to fight wind, throw forehand, or want a dependable finishing hook. Reach for the MD4 when you want a straighter line, an easier turnover, or more help at a lower arm speed.
