Agreed solid rollers serve a purpose and definitely can out power a hydraulic roller, I just don't see it in a cam this size and an engine with this rpm range. Now a mid 6 lift with duration in the 250-260 range is a different story. I had a friend lose a solid roller with pin oiling on street and it was really ugly. I intend 5000km per year with mine so the risk was not worth it to me.
