I've used a Logitech GPX for my entire gaming experience, but recently tried a Viper V3 Pro and was surprised by how much I enjoyed the roughly 10g weight reduction. Now I'm interested in trying an even lighter wireless mouse around 35–40g. I'm currently considering the Pulsar X2 Crazylight, Scyrox V8, and VXE Mad R, but I'd like advice on what to expect before making the jump. I'm 6'1" with fairly large hands and strongly prefer the GPX shape since I'm already accustomed to it. I'm especially interested in shape, durability, battery life, click and side-button quality, and wireless latency. Recommendations for other lightweight mice are welcome too.

The X2 Crazylight is probably one of the more sensible choices from your list if you want a real shell and a medium-sized mouse rather than an exposed-frame design. Just keep in mind that it won’t feel exactly like a GPX: the hump and side profile are different, so you may notice the change more than the weight. The Scyrox V8 and Mad R are also worth researching, but check current reviews for coating, button consistency, firmware, and battery behavior because ultralight releases can vary between batches.
The Corsair Sabre V2 Pro Ultralight is worth considering at around 36g and a relatively reasonable price. The main compromises seem to be mushier side buttons and somewhat higher wireless latency than the best-performing lightweight mice. Battery life is also a major advantage over some ultralight models, so it may be a better practical choice if you don’t want to charge constantly.
Shape databases and comparison tools are especially useful here. Compare the mice from the top, side, and rear instead of relying only on their listed dimensions. Also, don’t assume lighter automatically means better—some people find mice below 50g less stable, and the reduced weight can make aiming feel twitchy until they adjust.
I’d avoid jumping straight to something like the Zeromouse or other shell-less designs for your first ultralight mouse. They can be incredibly light, but the unusual grip and reduced protection make them more of a specialized choice. A conventional 35–40g mouse such as the Crazylight, a suitable G-Wolves model, or another GPX-like design would be an easier transition.
For mice in the 30–40g range, look at models from G-Wolves, the Mchose L7 Pro, and Ko-one. Some of these are extremely light, but shape matters more than the number on the scale. Since you like the GPX, compare the length, hump position, and width carefully before buying; an ultralight mouse with the wrong shape can feel worse than a slightly heavier mouse that fits your hand.
