Mass

Putt & Approach
MVP Disc Sports rates the Mass 4/2/0/3, calling the numbers tentative, and describes it as an overstable putter. On those numbers it has little glide, no high-speed turn and a strong finish; its ratings suggest it is less suited to players looking for a floaty approach or a turning line. In its October 26, 2026 description, MVP says the Mass shares the low-glide profile of discs like its Stasis and Range, in a slightly faster speed class, and that it was developed for players who want a lot of stability in a putt-and-approach disc, to make landing zones more accurate. MVP files it in its 10.5 mm putt-and-approach class. The PDGA approved the Mass on August 31, 2026 (certification 26-115, 175.1 g maximum weight), at a 21.1 cm diameter, a 1.6 cm height, a 1.2 cm rim depth and a 1.2 cm rim width. MVP's disc page, published October 26, 2026, presents the debut as the Neutron Mass in its 2026 GYROpalooza Box, with a triple-foil illustration from DoubleRam Design, in weights from 170 to 175 g. Try Discs lists it in Neutron.

Arm speed

NoviceIntermediatePro
SpeedHow hard the disc must be thrown to fly as designed. Putters are 1 to 3, the fastest drivers 14 and up.
4
GlideHow long the disc stays in the air. More glide means more distance from the same throw.
2
TurnHow much it drifts right early in flight (right-handed backhand). More negative, more drift.

FadeHow hard it hooks left as it slows down (right-handed backhand). Higher, stronger hook.

Dimensions

DiameterHow wide the disc is, edge to edge. Almost every disc is 21 to 22 cm.
21.1 cm
HeightHow tall the disc is lying flat. Putters are usually the tallest.
1.6 cm
Rim DepthHow deep the rim is underneath, where your fingers grip. Putters have the deepest rims.
1.2 cm
Rim ThicknessHow wide the rim is. Wider rims make faster discs that need a stronger throw.
1.2 cm
Rim Inside DiameterThe width of the flat middle, inside the rim. Bigger usually means a slower, easier disc.
18.6 cm
Rim Depth/Diameter RatioRim depth as a share of the disc's width. Higher means a deeper rim for its size.
5.7%
Rim ConfigurationA PDGA score for the shape of the edge. Low is sharp, like a driver. High is rounded, like a putter.
