I use everything that can give me an edge. What is and what is not worth the $$ that's my choice. I know my Deer sightings, kills, and deer that circle around me and then leave naturally have increased drastically since I have been using my current scent control regimen.
I will say that if you don't go at scent control 200% then you might as well do Nothing else other than just hunt the wind. It is much more than throwing on some clothes and spraying down.
