I love my First Lite Obsidian pants, stretches well in all the right spots and its merino wool which is hard to beat. I'm 5' 10" and thicc, so inseam is generally least of my concerns.
I'm in the "camo is all marketing" camp, my hunting clothes have to be functional, my obsidians are "dry earth" or brown, and a lot of times i wear my issued long sleeve multi-cam under-layer top. Solid olive/brown colored torso with multi-cam sleeves.
Play the wind, use the terrain, and keep your movements small and deliberate. If they see or wind you, no camo pattern in the world will get the shot you want.
My grandpa who taught me hunted in jeans and a flannel, and that guy ranks among the deadliest hunters I know of.
