Delrin LCA, and rod end struts are least compliant combination for sure, and with a rod end strut, the effective arc length is usually shortened, aggravating any needed compliance.
Two things come to mind that might offset the compliance direction of that combination, the user does not have reinforced LCA ( laugh2, don't get me started) and the on track suspension sees limited vertical movement, either mainly by smooth track surface, choice of Swaybar and/or TB, etc..

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
