I have been thinking about comparing the two for a while, since their specs seem to suggest such a comparison. Your post has now renewed my interest. Any major points from your side that you would like to have answered ?
EDIT: sorry, my mistake, I misread yor post, I have the 8.5x44 Kowa, not the 10.5x44, it makes little sense to compare with my Maven 11x45 (I could compare with the Zulu 9x45, but the Kowa would win single-handedly).
