Attraction scents.

Deer Kar

5 year old buck +
My kids are going to take turns sitting with me this weekend and I like to introduce different aspects of deer hunting to them. The 11 year old has manned the grunt tube and rattle bag for a few years now. We have also had fun with a standing buck and bedded doe decoy. I was thinking of adding a scent drag with some thing on it. It has been years since I have used any scents. Any suggestions ?
Wildlife research mega tarsal gland on one drag and special golden estrous on another has worked for me a couple times
I like buck bombs (estrus doe)
