Weight may be an issue with both of these. I cheaped out and bought the 35mm Pan and its a nice eyepiece indeed. Not up with the 31 Nagler, but so much cheaper. I do find it has barrel distortion at f5 which is a tad annoying when sweeping star fields, but really gives those big globs some extra depth!
I find that it is much better used with a paracor (but so is every eyepiece).
Given that we will not see the sky again this side of astrofest, you can try mine out there
