Personally I dont feel the "camo" pattern is as important as simple combat and placement knowledge is. If you can setup an ambush and your wearing any camo to match your surrounding area then you should be able to "make" an efficient cover to conceal yourself. The key to paintball isnt loading down in camoflauge, it's called individual angles(aka flanking). Catch your opponent from an angle and make him concentrate his fire in more then a 90 degree angle... if you get an opponent firing 180 degrees or more then many will get flustered and fall back or be eliminated.

But being as this question is about camo... The Military used woodland BDU's for 30+ years to fool enemies so Im sticking with what works. Woodland BDU pants and the famous Under Armor long sleeve turf gear.
