I quit using the Harland Sharp rockers because they were bushed and were breaking similarly and quite often with roller camshaft valve spring pressures. The all aluminum rockers have more material present and are thereby stronger than the bushed rockers. I would occaisionally break a non-bushed rocker (once every other year) but only after they were aged and cycled through pretty hard but no where with the same frequency as the Harland Sharps. But now that the Ersons are available, it's definitely a better route to go.
