As a (primarily) backpack/mountain hunter, the additional weight/size of a 40/42mm bin is a deal killer, and a harness is as well. The beauty of the 32mm is you can tuck them under your arm, or let them hang on your chest solo. Or, you can fasten them tight with a sternum strap... they’re just far simpler. I’ll give up the lost 4 minutes of viewing twice a day... I’ve yet to have that matter.
I certainly love the view of a 7x42 or 8x42, I just don’t want them around my neck for most of what I do.
Everything is a compromise weighted one way or another...
