when i share my sets with people they often complain that they are "too bouncy", yet when i drive their sets i think to myself, "feels about as responsive as a dead hooker".
i don't know if there is any real world use for an over-damped setup. maybe, just maybe, it might be useful for off road truck racing. those things get massive air, but stick like glue when they land, but even so, i don't know if you have to go over critical to get that behavior.
