Just a thought, Mel...

You maybe know there are discussions in books, etc about using
different types of pitch/lap for faster mirrors. Now that you're
working somewhat faster mirrors (F/3 in your case), I get the
idea you're thinking this is really not different than more
conventional F/ratios, like F/8, etc. In your experience thus
far, would you want to have thinner lap, or different consistency?

Dominic
