I have been messing with the 750 gov and the castle gov. Right now I am leaning towards the castle gov. It seems to work a little better. I have been tuning both governors, and think there is more I can get out of the 750, but the cattle is easier to set up and use. Important note is to set the throttle low and high end points and then calibrate the 750 low and high throttle in the gov expert menu.
