I'm kind of new to these big fixed blades but something between a Skinny Ash ~15.5oz and an NMSNFO/FSH ~20.5+oz. seems like a sweet spot to me. For me, a lot of it depends on the handle design. My FSH feels better, and lighter, than my NMSFNO, even though the weights are similar, I think just due to the handle. I love the handle on the Skinny Ash but the knife seems just a little light for a chopper and is more like a standard/utility knife. I love the handles on my S6/YG/YH and would really love to try a DF(someday). As far as using the knives, a good handle will allow the knife to be heavier, yet not as taxing on my hand and arm, if that makes sense.
