I'm with Rob...that's why my shed looks like a Cabelas store..I have tons of camo patterns for different situations..
Think about it....it's entirely (best camo) reliant on when (waht time of year), where (tree?, ground?, hardwoods? pines?, etc...).
As an example.....what do you wear in a blind?
There is no "best". Period. I'd feel more camouflaged in grey sweats against a big oak in December.....than I would be if I had on Mossy Oak Breakup.
