I'd personally use the Wildlife Research Center Dripper over the Tink's Dripper because the Tink's seems to drip to fast and empty after a day or two. As for what to put into the dripper, I like to use the Tink's Power Scrape or the Wildlife Research Center Golden Scrape. There is many different brands that you can try but thats just what I have used. The most important thing is trying to be as scent-free as possible while making the scrape.
Now the question...... do you pee in the scrapes you find? I just watched a buddy's self filmed I-Phone video of a 125" 8 pointer walk up to his human peed in scrape and stand there refreshing it for about five minutes.
