I have tried Tinks and most others without much success, I think the preservatives they use in the deer urine must change the natural odor. Two year ago, my boys and I started using products from Southern Whitetail Scents products and have harvested some really nice bucks using their products.We use the doe P for a cover scent and their Hyper Heat (freshly collected estrous) during th rut. Their stuff has no preservatives, is collected fresh during the current hunting season and is refrigerated to inhibit bacteria growth. check um out at www.southernwhitetailscents.com
