That lends credence to the theory that dry-down is caused by shrinkage.
Yes I do get rippled edges although they are mild. I dry mount my prints. One of the advantages I find to dry mounting is for easy showing of my prints. I just trim the prints and mount on an archival board without cutting an over mat. If I get a good reaction or feel the print is warranted then I'll cut an over mat. Prints show much better when mounted in some manner.

As far as dry-down the dryer dried prints seem to have very slightly better blacks and very slightly more dry-down effect. But the differences could be based on slight variations in dodging and burning and also toning.
