I have a friend who is/was a competent trap shooter, before we got him seriously addicted to Sporting Clays. He shoots his old trap Winchester 101 on the Sporting Clays course, even though it is bored IM & FULL. His scores are often higher than mine, and others in our group - notwirhstanding his tight chokes. It probably helps that he has used this 101 for 25+ years. If you are "ON", the extra choke constriction doesn't hurt a thing.

Those of us that aren'e as expert, do benefit from more open chokes.
