You answered your own question. This would be a good start. Some hunters try to stay away from strong estrous scents, but I find the best solution comes from trial and error. Personally I have had good results from a product called "Golden Estrus" you can buy it at Walmart. If the rut is on pretty hard, I would start anywhere from 4 or 5 hundred yards from my stand with the drag and refresh ever so often. Starting from a farther distance could help pick up a cruising buck that otherwise wouldnt even get close. Be sure to be as scent free as possible!! Avoid touching branches or undergrowth on the way in. As far as the can call...if you decide to use a "calling blind" technique, be sure not to over call. Hope this helps answer some of your questions. Good Luck!!

Also remember, does that are not in estrous will avoid estrous urine. If a buck is running a doe and see turns away for that reason, then he'll prob. follow her. On the other hand...if theres a lonely buck looking for a doe and hasnt yet found one...The scent will drive him up the wall!! The choice is yours.
