I use whatever I can get on clearance. Most of my stuff is either Mossy Oak Break Up, Obsession (spring and early fall), Advantage Max 4, Realtree Hardwood (do they make it anymore?), and HD. I have some specialty camo like Mossy Oak Forest Floor and Prairie Ghost.I believe anythingthat will break your outline is effective. For the most part, I'm more concerned about comfort (mesh and lightweight shirts in early season,thicker stuff in the late season).
