I think you are correct to be more worried about movement than scent. These days, with the proliferation of TV hunting shows and the abundance of scent related products being advertised on those shows, it is easy to overlook the most easily achieved method of overcoming an animal's nose -- hunt downwind from where you expect the animals to be! This is where good scouting can overcome even the worst cases of B.O.!
At the same time, if using scent controlling products (scent can't be eliminated, despite what some ads might claim) gives you more confidence in your hunting and if they add to your enjoyment, then by all means, use them.
I hunt with a guy who smokes constantly on stand, and given his success, I'm thinking of taking up smoking while hunting!
