I have started using pre-orbital with my mock scrapes the past 2 seasons and have really noticed an uptick in visits from bucks. The trick is to not add too much. Its easy for us to go a little crazy because we want to make sure the scent is there, but less is more in this case. They don't leave all that much when they rub their glands on it, so make sure to only add a couple drops to a licking branch. Whatever you do, stay away from Tinks. That stuff is a giant waste and I have NEVER had results using it. I've linked some of the stuff I use & have had good luck with below.
