Just to put a slightly finer point on the tip of the whip with which this dead horse is being beaten...
Due to apparent wind hitting the mast at different angles of incidence at various verticle heights, it is good practice to set the jib fairlead so that the 3 luff telltails break evenly. As the wind increases you should find the bottom telltail breaking first and should probably move the fairlead aft until all 3 telltails break evenly again. The barber hauler should be long enough not to affect this fairlead adjustment, but should only pull the jib clew inboard. If the barber hauler pulls down on the jibsheet it only complicates setting the jib.
