Simon, I've been following this string with interest, I also just got the FS100 and am having WB issues as well.
I was just at the Galapagos and didn't have much luck with MWB, it seemed to add to much red. The water wasn't the nice blue that you get at Socorro but more green to brownish at the thermocline.
I see all of your test pics. and am wondering what you were using for your WB card? White? Gray? The Sun? The Amphibico slate if so which side? Sand?
It made a big difference with my old Z1.

Thanks,

Monte
