Great topic, and honestly one that’s way more nuanced than the “lighter is always better” crowd tends to give it credit for. The core physics comes down to Newton’s second law—F=ma—where your finger and wrist apply force to accelerate the mouse. Lower mass means higher acceleration for the same muscular effort, which is exactly why the 60g class (and now sub-55g ultralights) took over competitive FPS. But here’s what most weight-reduction threads miss: it’s not just about total mass, it’s about mass distribution and rotational inertia. When you grind out a mouse shell and remove material from the top and sides, you’re shifting the center of gravity and changing the polar moment of inertia. For rapid micro-corrections—the tiny 2-5mm flicks you make at 800-1600 DPI during target tracking—lower rotational inertia around the tilt axis (Yaw/Pitch) is what actually makes the mouse feel “snappy.” A mouse that’s 62g but has its battery pushed forward can feel slower to stop than a 68g one with a centered mass profile, because of how the momentum carries through the deceleration phase. So yes, grind-and-hollow construction is great, but the battery placement and internal component layout matter just as much as the raw gram count.
Historically, we moved from the 100g+ optical mice of the mid-2010s (think Razer Naga, early Viper) straight through
