An interesting appraisal of the Dual ED eyepieces. I have a pair of 25mm that I use for wider field bino viewing. They do work quite well in the F8 and F9.4 refractors but do suffer from coma in the F6 newts, not unusable, as the outer 33% of the field is affected and can be ignored a lot of the time when concentrating on the central area of the FOV.
The shorter focal would be worth a look from what you say. Thanks for the write up.
