JPS,
I would say that your post is a fair summary of the Sport. The optics aren't top notch but I think that is what you get with one of the inexpensive "Permafocus" setups. I really haven't had any blurring problems exactly, though I will agree that it isn't a crisp image at farther distances.
But, if I was going to range longer distances then I probably would have bought the Pro 400, 600 or 800.
Like your last statement said...."for bowhunting it will work just fine"....
