Great topic. I’m 5’6” and about 160 lbs so I find straight cuts work best for me — on tapered cuts, there’s too much visual contrast between ankle and waist.
Totally agree on the s510. Just love that fit. I also like the fit on my samurai s0500, TCB 20s, and Oni 552 NIGR. The Stevenson overall 747 and Iron Heart 634s get a little less wear. I wish they were just a tad bigger in the thigh.
Honestly the best fitting pair I own are Carhartt double fronts in their original loose fit. The rise is perfect, and they look clean and not at all baggy.
