Digital BW, The Print

I just got an 8000, and wanting to see just how fine a superfine scan could be, 
I tried a 16x. I watched the progress window for a while then packed a bunch 
of equipment for a location shoot, watched a little longer then went home and 
had lunch, came back and watched some more, sent a few faxes and did 
some housekeeping. Then I watched some more. The scan was excellent. So 
was the one I got from 4x in a fraction of the time. What settings do you use for 
optimum ( a time vs. quality equasion) results. End use is best print I can 
make.
