I'm looking at getting a pair of 3sixteens, probably the ST-100x.  I have some APC NS in 31 that are just too loose (almost 501 like) after stretching, and I'm looking for a slimmer cut.  The jeans that fit me (5'10 170 34 waist) best are Levi's 513 in 32 and Uniqlo Slim in 32.  I was originally thinking to go with a 32, but since the ST-100x's are going to be a tad slimmer than these cuts should I go with a 33 instead?
