Seems that you are talking predominantly daytime use? Under those conditions, surely your pupils are no where near fully dilated (maybe only 2-3mm dilated at most?? Check some references?) so exit pupil is probably not an issue for this use. I'd suggest then that you go for the best eye relief and the best magnification at the smallest aperture that gives you a manageable weight to carry while walking. But if you wanted to use them to look at the night sky as well, that's a different story!

The reason for the difficulty is simply trying to decide the most important factors between eye-relief and exit pupil.
My wife and I wear glasses and are mid-30's.
So, is Eye relief or exit pupil of greater importance.
For the 10x50HR's:
Exit pupil = 5 mm
Eye-relief = 23 mm
Weight = 900g
For the 9x60's:
Exit pupil = 6.7 mm
Eye-relief = 21 mm
Weight = 1.2 kg
We will take these bushwalking and will most likely be lying down or against a rock when viewing.
thanks for any comments.
cheers,
DJDD
