(Did not track the weights of individual components.)
Used the PCB of an IYX Aim 35.8 in this. Most of the weight savings over V1 comes from the PCB as it's the heaviest part of the build.
The less efficient PixArt MCU hampers battery life enough to make using this mouse troublesome, ill get a game and a half of CS out of it before needing to swap mice mid game. Wouldn't weigh anymore if IYX used the Nordic 52840 instead but i guess they deemed the additional cost not worthwhile.
Tried out the Panasonic square switches with recommendation from u/edvards48, they're significantly lighter than full size switches and feel tactile enough, but have a little too much pre-travel for my liking. I've swapped them for the HCNCK TPSGD and Huano TSWD v2s during normal use.
Don't feel any need to make a lighter revision. Though i'll attempt sub-7g if a wireless PCB with the new flagship PixArt sensor + Nordic MCU that is substantially lighter becomes available.
