I have some sympathy for revolver shooters. But not a lot becuase they did it to themselves. But they usually don't whine about courses of fire. They just shoot them. I don't have any idea why someone could find that fun.
It's good practice for ICORE? In all seriousness though, shooting a revolver on a well designed USPSA stage isn't a headache, it just requires a lot of careful planning before you shoot. The worst thing that ever happened to me is I shot a popper that activated a disappearing target, and then forgot that I had fired an extra shot at the popper, so instead of having two rounds left in the gun for the swinging target, I had one. Whoops.
