Had this same debate over the years. My go to for years were Swaro EL's 10x42 and a Leica RF. Both excellent performers. But, I usually drop my pack for the final stalk or shot set up and my RF was on my pack belt(I don't like things hanging off my bino harness AT ALL). So it posed problems. I looked into options for RF binos. I ended up with the Zeiss RF 10x42 binos. All in its lighter than my El's and Leica RF together, they're always strapped to my chest so I can drop my pack wherever and its on me, and the glass was good enough to me to compare to my older El's. Now, the newer EL's would be better than the Zeiss RF binos but at the time, I had a pair of El's from 2008. So, as stated above, you do lose a bit when its a combined unit but I went with it for simplicity and ease(one less thing to forget). Oh, and I did Zeiss instead of Leica or Swaro RF binos also because I run the Outdoorsmans stuff and wanted the bino stud for mounting on tripods
