I used buck fever syntheitcs in a few mock scrapes last year. Worked pretty darn well. Out of the 5 I made 3 were tore up within 3 days of making them, the other two took a few weeks to catch on but ended up being used later in the pre rut. When you do make them be very scent free conscious. One screw up and the mock scrape is ruined. I also used the BF gland to spray above the scrape to imitate a licking branch and pre orbital glands being rubbed in the branches overhanging the scrape. Give it a try, I recommend it.
