Khales 10x40's, ride under my left arm with the strap over right shoulder. I own a "bra" set up and don't like them much now. Never had any problems with the under arm carry.

I don't like how the bino buddy makes your glass drag in the sand when you crawl. My eye cups are still all gritty as shit after crawling up to the tree I shot my baboon from. I plan on trying out a single leather strap...as soon as I get a single leather strap from somewhere. Maybe a strip of my buffalo back skin. Hmm...
