You'd get the same exit pupil with any 13mm focal length eyepiece in a given scope, so exit pupil is no reason to choose a Nagler over a bargain basement eyepiece of the same focal length. The Nagler's strength is superb sharpness and contrast across a huge 82 degree field of view, even in fast scopes.
