Here’s the thing..99.999% of the time I use 0 scent. I don’t like touching it, carrying it, messing with it, and it’s sort of a strange thing to use scent collected by a deer farm. If it disappeared I wouldn’t care. But, it can work in the right situations and I’ve used it in a few rare situations because nothing else would work.
As far as cover scents...it’s been explained that we smell cookies, and animals smell the individual ingredients in the cookie, I’ve tried cover scents as a kid and found it not effective IMO. I would think skunk is the only one that could actually overpowering but who knows.
