There's something about Wilderness with all black accessories and accents that just looks legit... has an army issued look to it.
Second place is Tombstone which also looks sharp, and you can run it with black limbs to switch it up. I like it better in AL than CF but both are nice.
Third place to me is black... it's kind of boreing but never a bad choice. Can always add your own color accents and black goes with everything.
Last place to me is Bourbon... some people like it, but it's not for me. I can see some areas of the country where it would blend with the environment, but I think a lighter tan buckskin type color would sell better.
