Cycling light target loads can be a problem with inertia driven guns like the Benelli's. I have proven this to several people at the trap club time and time again, my gas driven Beretta's cycles my very light trap loads while the Benelli will choke.
Other than that the Benelli auto'shave a great reputation for being a great gun. It sounds like you are going to have to find a happy medium, yes one gun can do all but one gun cant do everything equally.
