I am not a big scent guy.
But don' t over look doe in heat in October. There are always a small % of does that come into heat 28 days before the peek rut. In my area last year the beggining of Oct. had some great rut action - a good month before the peek.
Bucks grunting, chasing does responding to the rattle bag etc.
If in high pressure woods ,it doesn' t hurt to be the first one that season using such a scent before the mature bucks become educated by all the " Pee-Happy People"
