I am certainly no world renowned hunter, and I can only speak from my experiences over 21 of my 28 years on this earth. I used to feel like you do abou the rank of importance of those three things, but I have definitely changed.

First off, I think the scent control is way WAY overrated, at least from a "I have to shower with X soap and where Y clothes and use Z spray". The key is to use the wind. Even after a week in camp without a real shower, if the wind is good you are good. If it is bad on day one when you are all "scent free" then you are screwed. Using the wind is of #1 importance to me no matter what you are hunting.

I agree with the comfort assessment.

Camo is VERY important though and the proper employment of it is as well. The complete lack of movement will make up for "bad" camo, but we all have to move in order to take a shot. If I am busted, whether it be on the ground during a stalk, or in a tree after whitetail, I am almost always busted by them seeing me and not by them smelling me. What I mean by proper employment is using the right pattern for your surroundings, using available cover, and moving only when the animal permits.My home made ghillie suit is great out west in the grasses, but it stinks here in themidwest in a tree. I have used camo out westthat the mule deer can just flat out see.Even if I was sitting perfectly stillagainst a tree they would justsee me.Just my thougths thrown kind of at random.
