The 618 is finally starting to yield after the dunk. I think the dunk helped out a lot. It took about 3 days to FULLY dry out. Afterwards, it was a little stiff, but quickly started to relax. I have been wearing it for about 2 to 3 hours a day and also massaging and crumpling it by hand when not wearing it. More grain is starting to show after the dunk also.
