best way for using doe urine

I am new to using scents to lure deer, i was just wondering what you think is the best way to use doe or buck urine?

 

Regular doe p? I use as a cover scent, squirt it on the bottom of my boot when I get close to my stand. Doe in estrus use a drag rag. You could use a double drag, doe in estrus one and buck on the other. Make it smell like a buck is trailing a hot doe. It could lead one right to your stand.
