If your going with as complete as possible, depending on the ID of the focuser tube and the min/max height of the focuser, the .965" ep field stops are going to allow you to go pretty small on the secondary and still reach 75%(70%) illumination.
Fire up newt for the web and enter in as much data as you can in the specs' tab and read the help options, they are informative. Performance tab will show you the illuminated field values.

Thanks Steve, I will do all the math before starting on any serious rebuilding.
