I didn't want to use the 20m chinese ones again due to their tendency to start double clicking faster than others, i have no clue how the 50m variant behaves.
More importantly unless you have experience soldering i wouldn't recommend doing it on the G303, the PCB soaks up heat like crazy due to the thickness and material used (1.7 or 2mm FR4, double sided) and the lead free solder used makes it even harder.
The only difference I was seeing with the Japanese was the slightly higher resting notch and supposedly better build quality.
Wouldn't really call myself an expert but I have made some solder jobs throughout the years which still work fine today. But good call, may test on a donor mouse or 2 first.
