You do every little thing you can think of to tip the scales in your favor.
If just one time a grunt call brings in a Booner that wasn't aimed your way. Or one time scents or scent control make the difference for you it's worth it. And they KNOW THAT. THEY USE IT AGAINST US SELLING US ALL OF THIS STUFF.
I've got the carbon shirts and jacket but I think they do about as well as the rest of my stuff if I keep clean and scent free.
