We've seen the early stages of bearing failure with the popular trunnion bearing upgrades with any mildly aggressive cams. I seen the bearings start to deteriorate in as little as 4,000 miles so I've been looking for alternatives.
Straub Technologies has announced a bushing solution that I think has promise as a better solution for durability. I just sent a set of rockers to CHE Precision prior to finding the ones from Straub. I will use the CHE bushings in my wife's car and ordered a set from Straub for mine so we can compare the 2 to see if there's any difference. CHE charges $420 for the bushings and the installation and will not sell you the bushings to install yourself. Straub will sell you the shafts and bushings at the cost of $159.
