No matter what you are going to lift a little even its a few cm's. If you look at all the videos posted in this thread you can see a slight lift from the seat, even the SF video. I ride 46/16 and when I started ridding fixed I was "seat skidding" the second day of riding. just came kind of natural and easy for me.

BUT, I meantioned before when I was a kid in the late 70's I had bikes that were fixed wheel and to stop you had to skid using back pressure. Call it muscle memory I guess.
