garmis - the SL-200x will yield up to an inch of stretch in the waist, so it's best to buy the jeans tight in the waist initially so that they'll stretch out comfortably. They are slightly vanity sized so make sure you size down a size from your true waist measurement.
big punisher - the leg on the ST-210 is a lot slimmer than what you'd be used to on a APC NS; if you're looking for something more like that fit, you should look at the SL series. If you're a 28 in APC's I would suggest going with a size 29 or 30 in our jeans depending on how slim you'd like the fit to be. http://www.selfedge.com
