Hi guys:
I agree that all of your options are acceptable. And binoculars are "acceptable" or "unacceptable."
How much weight you are willing to carry, how durable the binocular will be years from now -- on these are what you make your choice.
I notice many of you prefer larger binoculars. I have used binoculars from 56 ounces naked to what I use now. My Zeiss 8x30 B/GA IF Olive (Classic) weighs 25 ounces, including strap, objective and ocular lens covers, and umbral lenses for viewing over snow. These ARE NOT the binocular you looked at. Since December 2001, they are available only in Europe. They are Zeiss' equivalent of a stone axe.
As you pass 40-45 years old, your pupils can dilate to only about 3.75 mm. So a binocular's ability to accommodate larger dilation becomes irrelevant.
First-quality 7x28s or 8x30s are acceptable for low light. And they are much more convenient to carrying as you get older, or hunt the high country on foot. The problem is unless you try a binocular at dusk or dawn for about 30 minutes, the only sure way to get quality is spend the bucks.
The good part is you spend once a lifetime.
