Something to consider: As you get older, your pupils' dilation becomes progressively less. After about age fifty, maximum dilation is about 3.75 mm. So having available a binocular that provides substantially greater light -- for example, 8 x 56s -- will yield somewhat greater side-to-side distortion free vision (you won't need to center your eyes as carefully within eye cups). But you will be using large, clumsy, heavy binocular.

Top-quality binocular is always preferred to budget priced. You need to buy only once a lifetime, so buy the best.
Most of the time hunting will be time invested LOOKING, looking through a binocular (in the West, anyway). Getting two telescopes to work together, and remain working together is not easy. If they get out of alignment, they become unusable -- headaches, double vision, etc. Top-quality binoculars stay aligned.
Also, top-quality binoculars generally have superior materials, superior optical glass, more precisely ground lenses.
I could go on, but you catch my drift.
I use Zeiss-Wetzlar 8 x 30 B/GA IF Olive binocular with F2 range finder. With strap, lens protectors, snow filters, these weigh about 25 ounces.
