Buy a breakup pattern you like and move on. If you read about breakup patterns and how they are designed to work, you will realize the actual colors used are not nearly as important as you would think. I prefer larger macro patterns as I think they are truer to the logic used to develop a breakup pattern, but I'm not fooling myself into thinking it really matters. As someone else said, it comes down to movement and the wind.
I honestly think this is one of the most overanalyzed things in hunting. People will buy boots without trying them and bows without shooting them but then agonize over small differences in camo patterns.
