#8 with my khaki suit... not sure if I'm liking the combination. Warning: Spoiler! (Click to show)
#8 does look a tad too dark for the suit in this pic, but it may just be due to the lighting. I bet this looks much better out in natural sunlight.
I can notice the difference just in this thumbnail image on my laptop screen - not something I would accept lightly in a +$600 shoe. Unfortunate =/
EDIT: Though you could probably even them out by simply placing the darker one outside under the sun.
