They may be a benefit for the occasional sporting clays shooter. They are not a benefit for serious registered sporting competition. However, they should not be a hindrance either. If a true pair is set up so that you have to shoot them so fast that going to the other trigger is a problem, then that is a poorly set pair of targets. I believe I can move from one trigger to the next just about as fast as a single trigger can reset. Certainly fast enough that it has never been a hindrance. But, I shoot a single trigger on my comp O/U gun, and would never consider going to double triggers on it.
