It's better to use a long reach brake at the short end of its reach, you get more mechanical advantage than by using a shorter reach brake at the maximum extent of its reach. Adding reach by filing the slots or using offset shoes obviously makes things worse, even without considering that both are inherently less safe than unmodified brakes.
