Replying to Bibs for tha backcountry

Heyo, I’m in the market for some new bibs. I’m mostly looking at the Flylow baker, Trew Capow, and Trew Trewth, does anyone have any experience with these? I primarily tour and am heading the direction of larger backcountry/mountaineering objectives but I also will be using these for resort skiing when I find myself in the resort. I’m in the PNW so snows pretty wet up here. I’m 5’10”, 170 lbs, waist width of 33. Ive heard various things about all 3 of these pants saying that they fit weird so I’m also not sure if i should go with an M or an L, but leaning more towards L. Any help is appreciated
