my take on it is that mix-n-match is fine, but if ya wanna be sure, add on some of the 3d stuff over the top... most of it seems pretty in expensive and imho is some of the best i've seen for woods... when i was in the infantry it was common for us to "camo-up" using leaves and branches attached to us, the 3D stuff is the much quieter and more functional version of that...
