Fantastic mod my guy, I have been waiting so long to see some creative weight reductions for this mouse. Planning on giving it a shot very soon. Quick question, looking into getting the drill bits you used to thin out the shell and bottom plate. Found these on amazon, a bit pricey tho. Just wanted to be sure these are similar to what you used.
