In my opinion your usin one of the best cover scents with HS earth scent.
when you get on stand pin a fresh earth wafer to your cap. also a little coon pee sprayed on each side of your tree will help. that earth scent smells just like dirt, so what better cover scent could you ask for? I don' t see where the smell of dirt, or coon urine could spook a deer, since they smell it all time anyway.
