Because I hunt here:
Can you tell if that's a billy or nanny with 8x? I can with 10x and it saves me a lot of leg work! That being said, it's about quality not quantity and given the same quality of glass, I'll take the 10x over the 8x any day as long as they both have decent objectives (42mm+) for good light gathering ability ( I realize that 10x70's would be more ideal but there's the weight issue to consider as well...).
Those are my old dependable Leupold Golden Ring 10x42's strapped to my chest, I wouldn't trade them for anything.
