Quick question. How come I am getting mass vignetting with really dark corners when using a 10 stop on my 24-105 when I see no vignetting and very nice corners on people using 16mm lenses...

I tend to get heavy vignetting as well, regardless of my lens or settings. I typically have at least one circular filter directly on the lens (either ND or CPL) and mount a 77mm wide-angle adapter for the foundation kit to that filter.
I just accept it as part of the constraints of using the 100x100's, so I try to frame to accommodate at least 10-20% cropping and then also fix the vignette via Raw adjustments. For example, here is the SOOC raw image from the shot above (click to enlarge):
I did crop this one more than usual, but very few of my long exposures go uncropped.
