Anyone who knows anything about camo understands that different conditions call for different types of camo. Terrain, world geography, even distance can drive the camo selection and be the difference between close quarters combat vs. battlefield type camos. The new digis work great in CQBs and the larger patterns work best across longer distances.

I think the most "unexploited" camos are naturally occurring in animal patterns. Tiger Stripe seems to be the only pattern that has caught on, but snakeskins, toads/frog patterns and even raccoons and other fuzzy animals have a natural camouflage that we can only wish to mimic. Think of anything you may have almost stepped on in the wild and use that!! I've got a set of tiger stripes that I have used for 2 decades and they are some of the most versatile camos out there (barring your not in a desert!).
