I've been following the CCO thread and just responded there, so I won't repeat that. While I don't own either of the bobtailed guns, I've played with a couple Cobra Carry pistols and a couple of non-bobbed Nighthawks. They are both quality pistols, but my vote would be for the Nighthawk.
As you mentioned, Nighthawk will make it the way YOU want it. On the snakeskin issue, call Nighthawk and ask them what the frontstrap options are. I have my doubts that they would do the snakeskin, but they may have something worked out with Brown, or they may have other options.
You also mentioned capacity. That's just a matter of which mags you want to use. I believe Nighthawk ships with 8 round ACT mags now. Not sure what Brown is doing, but I'd guess Brown 7 round mags.
On a side note, who in Michigan is carrying both Brown & Nighthawk. I'm from Midland originally and nobody around there ever carried higher end 1911's.
