as promised to jhwang37...here's some really quick (and i guess not very good, but i can't say i care at the moment because i'm still a bit buzzed at the moment) photos of how the mercer ii (black) looks on my 5'6" self...

i guess looking at the photos...the zipper area kind of curves/sticks out and away from my ankles...didn't really notice that in the past...but i still think it doesn't look too bad.
if i'm just wearing the pants normally, the "bottom" portion starts off maybe 1 inch to 1 1/2 inches below the bottom of my kneecap. if i purposely pull the bottom of the pant legs down, there's a good 4 inches or so before the "bottom" portion starts (which in your case "bottom" would mean the camo portion for the mercer ii drop on monday)...so there you have it...
hope this helps (if even just a little bit) to make up your mind on whether you want to shell out the money for a pair or not. i still personally think it's worth it (be mindful that you're talkin' to someone who has 4 pairs of mercers, and 2 pairs of mercer ii's...so i may be biased...haha)...
