It's lighter than my previous 25x100.

I rarely have it "on my chest"

, I usually just mount it, same as you would do with a 20x80.
Although, I do hand hold it, from a sitting position, on occasion. Gives new meaning to the phrase 'bosom buddy'

BTW a 20x80 Triplet weighs almost as much as the 20x90.

Just had to kinda get that "off my chest".
