Thanks, Mark! That was actually with the DA15... accidentally posted it to this thread, whoops.
That's quite a shot of your own there; I love the colors and the soft tones in all that fog you seem to find yourself shooting in all the time. As for using your GNDs on the 31... I have definitely seen discussion on that before:

Not sure if that link will work because PF blocked outgoing links to DPR last year at some point for a while, but it's basically what gtl says above: break the glass out of a few cheap filters (three I guess), and screw them on in a stack. Cokin filter holder should be able to fit on the last one... Certainly not elegant, but it's a fix.
@gtl -- I picked up a small set of Cokin P-sized Singh-Ray GNDs and like them a lot so far. A 2-stop hard transition, 3-stop soft, and 3-stop reverse GND.
