You may be loosing the equivalent of 3 f-stops of light with all extension tubes together so you may find the AF on your slower lenses hunting.
Have you got an external flashgun or ideally a ringflash so your not forced to shoot with the largest aperture resulting that very shallow depth of focus.

Hi Phil
I don't tend to use 3 together as on most of my lenses focus is about 2mm from the lens filter. What I'm finding is it's difficult to focus and twisting the zoom ring is the only way to focus. Do you think I should use the 50mm?
