Okay. So I got my new pants today and maybe this will help some people out who still haven't ordered. I'm 5'10", 210 (calm down ladies.) I recently got three pairs off HM and had one here already:
Large CCM 7000 - Too snug for my liking, particularly in the gut. Everywhere else was fine comfort wise but as soon as I leaned forward, bleh. Pants were upper to middle knee on me.
XL Reebok 7000 - Fit very nice around the hips/belly. Felt looser throughout the rest of the pants. Height seems fine though. Middle of the knee to lower middle.
Large CCM 520 - Fit nice around the torso, legs and rest of pants feel very nice as well. Height was around upper knee. I could actually tighten the pants all the way and it was still fine (not ideal, but definitely doable.)
XL CCM 1052 (Older 520) - Too big all around. Slipped down on me just standing here. Couldn't crank them tight enough. Middle to lower knee in height.
Hope that helps. All measurements and comments on comfort were, of course, based on how I prefer my pants to fit. It's all PP at the end of the day!
