Well plenty will not like what I have to say. Keep it simple.
Look I use to sneak all over the woods for deer and elk. I used every cover sent , heat scent on the market.
Five years ago i just said the heck with it all. Now I do 2 things. I shower every night or wipe down with wipes and i use primos secent away. And I sit. I go to were I know animals pass and i sit. Two years ago I killed a spike elk while it stood 6 inches in front of my hub blind. Before he came along 2 cows brushed as they moved away from hunters above me. And a big bull came by. Last year a cow walked right up and if I had not moved sudden I would have tagged her. i ended up killing a 400 lb elk on a Master Hunter tag after sitting in the snow for 8 hours. Deer hunting I saw no bucks but had 11 does file by at 5 ft. And I was sitting in plain veiw.
Really if you are in a area with elk and there is hunting pressure sitting,not moving works best for me.

One of the best cover scents is camp fire smoke. And given this year that might work real well in some areas.
