Inertia

The Inertia is an understable MVP distance driver rated 9/5/-2/2. At speed 9 it is a step down from full-speed distance drivers, and its -2 turn lets it drift right for a right-hand backhand before a moderate fade brings it back. MVP aims it at lower-powered throwers looking for distance with control, and at stronger players who want turnover lines and hyzer flips. Players who need a driver to hold a stable line into a headwind should look at something more overstable. MVP describes the flight as responsive and understable with a dependable fade: low- and average-power throwers get a straight-to-understable precision driver, while power throwers can work it through a range of turnover lines that still finish with some fade. In practice it is a disc for hyzer flips and long anhyzer shapes rather than for fighting the wind. The PDGA approved the Inertia on 10 February 2014 (14-07). MVP introduced it as the debut of a new class of controllable distance drivers, and a Neutron Inertia was the PDGA's 2015 membership disc. In 2026 MVP refreshed its stock stamp through Project Lab Coat, which MVP says changes the look only, not the flight or the plastic. On our comparison table it lines up with the Prodigy FX-4 and the Innova Valkyrie. Try Discs lists it in Neutron, Proton, Plasma and Fission as of October 2026.
