[Desert Fox]

Personaly, I found the Smokey Branch the most versatile pattern , and the smokey is very close from the multicam.I took many pictures, and I often bring a curved bicycle mirror, and in all the terrains/weathers I tried, the smokey was very effective.
I think the multicam is better than the smokey.
The Cadpat is the best for canadian SUMMER time, but is not effective at all during fall, winter, and even spring.The Cadpat is just TOO much green for anything else than summer.And it is usually too much dark also.The Marpat is a better choice I think.The new USArmy pattern is also better than the CadPat, because it looks like a used canadian cadpat. And in the field some people prefer to wear a used 'whitened' cadpat.
I prefer a pattern too much bright than too much dark, because it's easier to darkening (e.g. mud) than whitening.
