Benelli Vinci and Beretta Extreme 2 are not really trap/skeet guns. They are field guns and will do trap/skeet okay, but not don't have the accessories and components to excel like a proper competition gun would.
If you like the Vinci, look into the Vinci SuperSport. Otherwise, get a SuperSport, Sport II or Legacy.
For Berettas, look into an AL391 Urika Parallel, AL391 Teknys Gold or A400 Xcel.
