I've killed 2 big bucks that I attribute directly to Tinks69 (although any good doe in estrous probably would have worked) and both were at the tail end of the rut, I think when most of the does had been bred and the bucks were looking for those last few in estrous. I also have had lots of small yearling type bucks come to it during the pre rut, probably because they hadn't started getting kicked around by the big boys yet. I now only use it the last part of the rut, the first part I use just a grunt tube, the rest of the season I try to be invisible.
