>>> multiple optimized upper ends <<<

the pros do this - the several amateur installs that do this that I have
seen all run into the same problem - they do not like to mess with
changing upper ends during the evening observing, so they end up never
changing their upper ends - if someone could work out a good design that
took only seconds to change out, that would really help
