I have had pretty good sucess with the Code Blue Doe in Estrous scents. Last was the first year I used it and had numerous bucks follow my scent trails and work over scrapes I place scent in. Code Blue is what I will be using this year also. I had previously used Tinks and had very very limited succcess with it. I have also used James Valley Scents Lethal Weapon and have decent seccess with that.
