It will break up your pattern but then again so will any other camo pattern out there. Don't sweat it, pick a pattern you like and remember that it's movement that is going to give you away, not your camo pattern.
By the way, I've had several successful antelope hunts in Wyoming and wear my normal woodland camo. No antelope has shown any concern that I look like a hardwood tree with a splash of evergreen spruce instead of a sage bush.
