hmmm. Reds or Blacks for typing?
Why not both
Just recently, I used a SteelSeries 7G (MX blacks, just to give them a whirl) at a lan party and it was starting to fatiguing my fingers after two hours. When I when back to my CM with Reds, my fingers began rejoicing.
And as a side note, Reds + PBT == butter smooth typing.
Edit: Tinlong- How many more you need to fill the next carton of 20?
