I have constantly experimented with different chokes at Sporting. Amazed at hitting 40+ yard targets with no choke and very open chokes. Also amazed sometime at hitting close targets with tight chokes. Still unless you are extremely good, like George Digweed good I think Full C is a disadvantage.
It depends on the percentage of targets you are willing to lose due to a thin pattern that will not break ALL the targets statistically.
A statistical certainty of a 100% score on long handicap trap targets didn't exist until the shot wrapper combined with hard shot made it's appearance.
Experiments show that 70% patterns at the plane of the target are required to assure the target breaks.
As you observe, a percentage (even a high percentage) of long-ish distance targets will be broken with more open chokes. They just won't ALL be broken, and this of course is what a serious competitive shooter requires.
