1200 oz-in servos are overkill for a BP. I have 850 oz-in servos with 2.5:1 reduction and 4-pitch screws, and I can break tools all day long without losing position. And, it'll do 400 IPM rapids. With 1200 oz-in servos, you'll gain nothing in performance, and increase the chances of breaking the machine if something goes wrong. Bigger isn't always better.
