Not using it, however. +Mining speed makes it seem non-legit, and mods that change IC functionality in general (besides the non-fail wrench, because fuck that) don't taste good to me.
100% agree on the upgraded wrench being fail-proof.
The increased mining speed is also something that wasn't needed; the drill it's self is supposed to be the limiting factor.
