I've been wearing Predator for years now, and really believe in it. Personally, I prefer the fall brown and think it is the best all around pattern. Spring green is great in the spring for turkeys and in the early fall.
As far as the animals go, I think it all works great. Large patterns really helps to break up the human outline, and that is the most important element of camo. I can't tell you how many times I have had animals look directly at me and after studying for a bit, just go back about their business.
Gray Wolf has great Predator clothing. The wool is marvelous of course, as is the Wolfskin fabric. But he also carries fleece and regular cotton in many of the patterns as well. Best of all, he is a Trad Gang sponsor!
