I was wondering the same. My brother has one with the more greenish colors he uses for turkey hunting. Im leaning toward the more desert colors like yourself because the brown and tan colors would probably blend in more with the oak and hardwood colors that I normally hunt in the fall. But I could be wrong. Maybe just buy both!
I've got the Desert Shaggie from Rancho Safari and the Desert one from AllPredatorCalls, like the photos above. We use both of them all the time. If you hunt in grassy areas, they can't be beat!
I own a bush-rag and i blend my own colors that match the suroundings if ya dont match you will stick out like a sore thumb... The last couple pictures look ok except for the rifles not being camo'd up...
