All right, you dream killers. I started measuring and really taking a look at my jeans/body.
Guess I was wrong and my waist is now measuring out at a 31, so a size up of 1 to the 513.
Measured the 513s tagged at a 32 x 34:

Thigh: 11 (I can afford to lose 1 to 1.5 inches before it starts to hug my thighs)
Knee: 8 (roomy all the way down from here to my ankles after this, I can afford to lose 2 - 3 inches on my calves...
