Tigger's right, FR5 works pretty well the way it is. Nothing is perfect, but I do see this as the most efficient. I kind of like AD's suggestion of making it either permanent or temporary, but I also see that as dangerous. I've had a few years to practice using FR5's so I've learned to be careful with them. They work well but they can also be a harsh punishment for something that can be handled other ways.
There are more than a few FR5's I've regretted. I don't file them in haste or anger anymore. Mostly I do it when the consequences for Junkers will be worse for not doing it, or when someone makes it quite clear that they have no respect for RP at all. (The only case is should be permanent in my opinion)
