I've never had issues with OJ wheels holding bearings. I commute 6kms to and from work and use 87A keyframes. I skate the same set up in a park near work at lunch time and have gotten use to riding softer wheels. So much so, I prefer softer duro these days, but put this down to familiarity. I have another setup with 95A nomads and I'm satisfied with them. Both slide fine, it's just a matter of getting use to the wheels. I've experienced harder duro wheels chipping, which make for an unpleasant experience.
