I use a 40D on an EQ6 and don't bother with the mirror lock up. I start guiding before I start the exposure and can watch the guide star in real time using guidemaster. When the exposure starts there is no discernible movement of the guide star so don't see that I have anything to gain by using the mirror lock.
If your setup isn't as heavy then it might be needed.
