I think you will find that the nocks are the same size. Fat boys use a uni bush and G nock.
Ask your self this question 'If you were shooting ACE's out side and X7's indoors what would you change?' If the nocks were about the same thickness you would drop the arrow rest and line up the arrow with the center of the button. Compound archers mostly don't use a button so do not have a a visible reference for arrow height. I shoot off fingers so my compound is fitted with a mag flipper rest and button.
