rocks101,
First off, what do you plan to use this on? There are tables on critical lengths vs speed etc that you have to look at. Secondly, the change between the typical 5 TPI and 10TPI will also affect speed. Thirdly, the coeficient of friction between ball and lead screw is great. This will affect the required power to move the axis.
Why not use the ball screw and make a pre-loaded nut??? I did and it was fairly easy to do. Zero Backlash.
To possibly answer your origional question, I was told by Roton their rolled ballscrew single nut had a typical .006" backlash!
