Only benefit to a heim, as I understand it, is less compliance at the pivot point. A rubber, and to lesser extent poly, strut rod bushing will compress and relax in addition to twist as the strut rod goes thru up/down and braking/unlaoding forces. A heim doesn't compress/relax, at least it doesn't till it wears.
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.
