I'm working on a 6" f/4.5 primary, and its been hard to get
all the zones behaving well...so, when does it make more
sense to take it back to spherical and start again, or to
continue futzing (sp?) with the figure to try to bring it
around? I'm worried it may not be 'smooth' in the latter
case. Suggestions? At the moment, the center depth is about
right, but too flat, and the edge is high...

Doug
