With a lot of purchases to make between now and October, i am starting with binoculars. So, i am looking for input on the optimum size...what ya'll think is the best for you and why. I am speaking of a pair of binos that you would wear on your harness, not large, truck window optics....One pair is for my wife and she will need to go as light as possible so consider what smallest and largest size you would choose to tote..

Thanks in advance.
