Do both. When you start a mock scrape you'll want to put about an ounce of scent right in the scrape. Then hang a scent dripper with about 4oz of scent in it. Most drippers work with temprature fluctation so they will drip scent durring the warmer daylight hours. This (if given time) should condition the deer to check durring the daytime and give you a better shot at noctournal animal.

Most importantly, Don't forget the licking branch!
