if the upper balljoint angle is flat, by that I mean not up or down in relation to the bushings or mounting points, you will have plenty of travel and no binding even on stock balljoints.
the lower balljoints should be tilted back at the top about 4 or 5 degrees and you will have no binding.
the arms will be close to bottomed out at layed lout and go way up till the bags top out and still have travel on stock balljoints, no matter who makes them.
there is NEVER a need for uniballs or other joints other than looks. when the truck is layed out the balljoints should be at almost bottom travel.
