Scent to attract you want upwind to avoid your scent being detected,place it where you want deer to be for a shot. When dragging scent stay away from your stand(imagine a deer following it) and drag it upwind of your stand to where you want deer to find it,leave it there during your hunt.
A cover scent can be with you or a couple feet upwind.(skunk is a bummer).
Your choice of drag scent(s) seem alright,wear clean rubber boots with pants tucked in and don,t touch (leave your scent) on anything.
Keep in mind when choosing your path to drag,sometimes it gets found and followed backwards.
Scent being dragged can weaken from beginning to end,causing deer to follow stronger scent direction. So be sure path of drag offers a shot or two just in case.
Good luck.
