Hi, i´ve got a bf20 with its original screws, now i´m planning to change this screws by ballscrews, before buy them i would like to know if anybody has bought the original OPTIMUM ballscrews (page 134):

¿What is the pitch?¿how many backlash?¿run smoothly?¿are easy to assembly in the BF20?¿do you recomend me this ballscrew or there are others better and cheaper?
