If you're looking for a heavyweight slim/straight khaki, I can recommend the new Studio D'Artisan
I went TTS with the 32's -- they aren't tapered but the top block is pretty fitted and I'd say it's a medium-low rise. Not for those with chunky thighs.
Fit aside, the fabric is phenomenal; it's mercerized and looks to be around 11-12oz. At $185 they aren't cheap, though, but I'd guess they'll wear like iron.
Edit: Got 2 compliments from random women...
