upwind dominant buck should not spook him,but it might i would use regular doe urine wright now. later closer to rut try estrous urine.you can get a deer decoy it will add + bonus to your setup.plus the buck will feel safer to. whatever scent you use it should work in the scrape.makes sure that it is buck urine most of the time every once in a while use doe urine in the scrape.calling helps but if it is not the rut yet use the doe bleat call.or use real soft grunts.
go deep hunt hard.
