All good advice. I would think about why the deer are in there waiting for you. Is it a feeding area or a bedding area? It may be that you want to try it as an evening spot.
If you are seeing or hearing the deer in the area I would keep after it. Many times they will run off and come back later.
Something else I would consider is how high are you are in the tree. I have found that 20 feet is my best hieght.
I would wait about using the calls and rattles until you have heard the deer do the same then you can better replicate. Very little goes a long way.
Leave all the scents at home.
Wash clothes in a hunting wash often and use the UV treatment once. The rest of the cover scent I would do without.
Just my 2cents
