ASAT, Predator (most patterns), Kuiu (Vias and Verdes), Cabela's Outfitter, Sitka (Open Country, Mothwing and Forest), Mossy Oak Treestand, Realtree Max 1, Cabela's Open Country, Skyline Horizon.
All of the above are fairly open patterns, which I think are the most effective. This selection will effectively cover just about any bowhunting situation, but the pattern should be chosen to blend into the dominant surroundings, just like "matching the hatch" in the flyfishing world. For instance, the Skyline Horizon is perfect for late-season treestand hunting in hardwoods and for hunting on the ground in snowy conditions, but it is far too light in color for most other conditions. The Max 1 and Cabela's Open Country are ideal for hunting the open grass flats and creek bottoms in the Northern Territory of Australia for buffalo and boar. And so it goes for the other patterns.
Wool solids and plaids are good too, but when the weather is warm, only the light Merino shirts are comfortable, and wool has its own disadvantages (along with many advantages). The biggest problem for the traveling hunter is wool's bulk and weight, which is why the clothing companies like Kuiu and Sitka do not use wool in their mountain clothing except for the thin base layers, where Merino wool excels above any other material. But this thread is about camo patterns, not materials, and there are wool products that incorporate some of the patterns I have listed (and other good patterns).
The main things are getting out to the places where the animals live, staying downwind, and keeping noise and movement at a minimum. Do remember that turkeys see color and have fantastic vision, so picking colors that blend into the surroundings is vital when turkey hunting, although it is not so important when hunting ungulates that do not have much color vision.
