I' ve used scent drippers with pretty good success. Early in the season, I use buck urine as a curiosity scent, then switch to doe in rut AND buck urine when the rut is on. I' ll hang two drippers over the scrape when I do that. The combination of doe in rut, and buck urine has usually produced a buck trying to find out who' s tappin his honeys.

Sorry, forgot about the rest of your question. Good ol' Tinks 69 works good and I use the Code Blue buck urine.
