I know this gets asked to death, but I am stingy guy in a town where nobody sells APC. I am a size 32 waist, 5'11", 160lbs, is sizing down done by just 2 sizes? I don't know if I want the skinny of NC or if I want the NPS. I currently like my 511s the most, though I wouldn't mind a bit skinnier. Basically, I ordered NPS in 30 and NC in 30, and I can button the NPS all the way but the NC I can't get past the second or third button, though I can say I have tried for more than a few minutes. Basically, I would like to know if the NPS, with stretch accounted for, will stay fairly slim like 511s or if NC can stretch to have a little bit of slack in them. Right now the knee doesn't seem to be too tight(ie I might prefer it a bit tighter) on the NPS but I'm not the tallest guy so I don't know what it will look like once hemmed and stretched, etc. I know you can't predict the future, but if I am committing to a pair of jeans that costs a decent amount of money, I would like to make the best purchase possible. Thanks for any help.
