I doubt you will be disappointed with the S&B performance.
Magnification definitely is an asset in low light, particularly as one gets older. Personally, a 5mm EP in a 42mm or 50mm objective works well for me in low light for WT -- slightly dimmer than 6x in the same scope, but the higher magnification will show more detail. I was perfectly happy with killing at 6x in my 30's & 40's but ongoing comparisons are compelling. Your eyeballs do not improve with age.
I never had an 8x56 bino when I was younger, but I imagine it would have been a great asset, particularly to a guy with excellent vision. Of late have been putting a 10x56 to good use in the lowlands.
There is little contest between a 6x30 bino and a 10x50 in low light judging a set of antlers...both have EPs of 5...of course we all can get by with a recurve in low light with no optics at all...:)
