TIME FOR A CURVE BALL!!!
I have been deceitful guys...I did not mention one thing...
Many times, the GREATEST of all positions i think, is to take the keyboard entirely off the desk and have it flat on your lap. typing that way.
Maybe its not the fastest configuration in terms of WPM because of how much more relaxed you are...but it feels so much better.
With the filco black swtich on my lap, i can feel the keys sliding up and down on my lap, vibrations transferring through the board to the bottom, its so awesome =P
