Does anyone have a source for a 67mm male to male adapter so I can mount two CPL filters female side to female side?

I see you've already given up on this, but I'll put the link here for anyone else who might be experimenting

That's a common adapter, although not normally used for this purpose. As you've noticed, it doesn't work that well. You might try a couple of different polarizers, some work better than others.

What do you think about a linear polarizer and a circular (on the camera side) Joseph?  The circular might cancel the detrimental effects of the linear in digital while reducing any patterning.  Either way I can't really see economic benefits to using polarizers to replace gradient filters.  Seems like a long way to a dead end but it's a curiosity.

..oh, and I see by the lack of responses that I am right yet again.
