One of the best things I've used for scents is cutting of the tarsal glands of a doe as close as I can get her to the start of the rut if not already with the rut in progress, and only if she is walking alone. I'll cut if off, package it and then take it home and freeze it. Let it thaw out when I'm ready to use it and now you have an actual, one doe, one scent lure. If you can't get to tarsal glands I've seemed to have the most luck with the 69 estrous. That's also in a relatively normal do to buck ratio like 2 to 1 and so on. When there is so many does running around, your going to have to find something else as a lure. Why would a buck come to your doe lure when he is already following one in heat.
