Leave them attached and don't try to move the leaves into a more presentable position. Remove them if they die.They will continue to put energy back into the plant until they turn completely brown.

Del, is that really true? Or will the plant continue to put energy into the leaves, trying to preserve/save them? Is there good science behind leaving stressed leaves on the bulb? I have always likened it to deadheading perennials: I remove poor-looking leaves as soon as they turn yellow. My thought process was, like dead flower heads, the plant doesn't need to continue carrying that burden. But I want to learn if I am doing it wrong.

I try to remove leaves only, when they are really yellow and dry and thats the plants will. This way is the only for the plant, to waste substances not needed anymore. Thats their garbage can!
