i used tinks power scrape-mock scrape starter last year and it worked VERY well. As said make sure you have an overhanging lickin branch. A good bet is to set up your scrape where there have been scrapes in past years-i have several spots where scrapes have been under the same branch year after year. Once established and the rut draws closer i switch over to a doe in heat buck urine combo. If you really want to torque em up take some dirt out of a scrape in a different hunting area and put it in your scrape and watch what happens!!!! Not to mention its free and 100% fresh. Make sure to use rubber gloves when doin anything with a scrape!!! Mock scrapes are probably my favorite pre rut tactic to use- if you know what you are doing it can be very productive.
