I just recently did a research for 12mm - 18mm eyepieces with 68 - 82 degrees FOV for myself and according to a few reputable reviews, including one made on an optical bench at an optical R&D facility rather than just a scope, the 12.5mm and 14mm Morpheus are the worst in the line in terms of field curvature and aberrations even in 1:10 scopes.
On the other side Morpheus 4.5mm, 6.5mm and 9mm are absolutely fantastic even in 1:4 scopes!
