I dont typically follow scents that much, but I can offer what I do know.
For starters, I am presuming your are hunting whitetails, because it seems not alot of yall hunt mulies. they are a VERY keen sense of smell. Most important thing to remember is to watch your wind. If you have strong wind in your face, theyw ont smell you and spook. Look into things such as scent lok clothing (not really necessary imho) and cover scents. What kind of garbage bag are you using? You should know that alotof garbage bags are treated with chemicals to deal with rotting garbage smell and crap like that. Finally, you coul consider over scents like doe estrus instead of just mask scents.

Hope I helped a little!
