I find with draggin jeans that they are a bit tighter on the waist than the same size in ordinary denim jeans- I put it down to the kevlar lining inside.
Maybe try one size up. Length is not an issue IMO.
Cedarbrook, have you seen Hood jeans in your area...they are only available on Internet, direct from the manufacturer...but maybe you or some of your riding pals like Hobbit may have sampled them?
