Personally I am a Sitka guy.
As mentioned above, most camo patterns are way to dark and blend into a dark blob and make you more silhouetted.
I was watching a guy with my naked eye walking through sagebrush at about 600 yards away last year and thought he stood out like a sore thumb. I looked at him through my spotter and to my surprise, he was dressed head to toe in Kuiu.
Sitka is a light camo patter with a lot of grey in it with I'll take over darker tones of greens, browns and blacks.
My philosophy is to always match the ground cover because thats what you are standing in, not the trees.
I'd have to say we are in sagebrush 90% of the time no matter what elevation we are in, and it is tones of grey's.
But also as mentioned above, no camo will be effective if the wind isn't right, nor will any scent blocker even remotely help.
