Replying to Should I go L or XL Saga Fatigue Pants?

Yo Duders, I have been cruising threads but haven't been able to figure out how this years saga fatigue pants fit...i've also looked at the size chart on their website but it looks like L and XL are the same waist size.

What size pants should I get if I'm 6' tall and weight 170 lbs with an athletic build? I want them to be pretty slim, but not 'tight'. Any suggestions are appreciated, or better yet pics would be rad. Thanks in advance.
