For me it is easy: If your crystal does not diffract, you have a problem with your crystal, which is usually very difficult to optimize If you have no crystal in your loop, you have a problem with fishing your crystal, which should be much easier to optimize!

Dear all I had one interesting comment today at the beamline, that I would like to share with you for your advice on how to answer this... Is it better to have no diffraction from a crystal you shoot, or to have no crystal in the loop? Hum, difficult one...
