another bino eyepiece question

Thinking of getting a pair of 25mm plossls for my Andrews bino. Has anyone tried the GSO 20mm superviews or similar 65 degree eyepieces with this unit? The exit openings just before the eyepiece is 20mm, same as William Optic bino. I am concerned about vignetting before the field stops. Thanks.
