Its all about putting your stand(s) in the right spot(s). Your putting to much emphasis on the gimmicks. Stand placement is going to make you sucessfull faster than any call or scents. The scents and calls you mentioned can be used as a tool but to many young hunters are blowing them every ten minutes giving away their position. I would recomend making yourself a ghost. If you use a call only do it when you see a deer you want to kill. Just a light grunt to get his attention.Maybe just a couple of other guidence grunts if he seems interested. If you use scents put them in spots where you want to get a shot. The idea being adeer comes in puts its nose on your scent and you draw. Theres no magic potion that will float into the woods and bring the bucks to your stand. Stand placement first, than the tools.
