Standard sensor, using 1000hz polling rate. Considered changing sensor, maybe the newer 3.0.
Replaced cable setup two times, feet every 12 months or more sometimes, using mousewheel assembly out of a logitech g500, and in general always servicing it.
Took some weight out too, but so long ago i forgot what it was.
Tried various switches too for mouse buttons, pretty sure the ones i left in arent the stock ones, they're pretty chopped and shaved up.
