Maybe AIP thought that a rolling bearing guides smoother than the heart shaped roller? To be honest, I find the heart shape roller better, its more dynamic than the bearing.... However, you can always reduce the nub on the bbu so there is less resistance when it rubs on the bearing. Mind you though, if you take off the nub too much, your hammer wont cock (ie. be caught by the sear), as such, I suggest you use caution if you do sand off the nub.
