The Sage Graphite III RPL was the rod that made Sage famous and was the rod that brought the "fast" rod into being as the tool we have used since.  This RPL+ came next and has a more progressive taper thus making it even more effective at bucking wind and delivering heavy or wind resistant flies.  It does require good casting technique at short distances to load.  The post cast stability of this rod is excellent which aides casting accuracy and decreases fatigue. This rod has been used very little and is excellent condition.
