Green bearings or stock adjustable

The green style bearings have balls in them, The Ford 9 inch uses straight rollers in their bearings, at least from what I remember. I used 3 sets of Green bearings and I don't believe I got close to 10,000 miles out of any of them. I will never use another set of the Greens! Does anyone use BALL bearings on their front brake hubs? I don't think so! That went out in the 50's.
