I'll have to agree with Dave. But have to say, different hunting areas mean different hunting tactics. There's not one true receipe that fits all situations. Buck/doe ratios can play havoc with hunting stratagies. If your area has a good or high buck population then I would say scents may work for you (results may vary). Some folks have better luck than others that use scents. As for myself, I'm convinced scents make a differance, but my area has a high buck population. Here is one example from last years hunt. Located a natural scrape, used four to five drops of "Active Scrape" from Wildlife Research Center and single doe estrous per visit in the scrape. Started doctoring the scrape on October 25th and renewed the scrape on 3 to 4 day intervals, but used scents in combination (sometimes both and sometimes only one scent). I never used the scent bombs. Most important thing is not to contaminate the scrape site with human odor. I used Scent Killer-Autumn Formula made by Wildlife Reasearch Center. It smells like fresh dirt. I spray my shoes, clothes, gear and the bottom of boots before I get to the stand and again before I approach the scrape. Pre-rut starts in my area around November 5th. Final results - Five bucks in three days during the hours of 1:00 - 3:00 p.m. and four of the five were takers. On day three (Nov 11th) I shot a 140 whitetail. But the catch is, the 140 was the only one to actually go to the scrape. I just let the scents work and I did not grunt call or rattle. IMO, using scents from dominant bucks elliminate the smaller bucks. The smaller bucks will still cruise through, but will only mark areas with urine in the area of the scrape in most cases and from my experience. Which goes back to what I think Dave is saying. If the smell is too dominant, then no buck will compete with the scrape.
This year, I'm trying out some new doe scents from Code Blue. But will still use the Active Scrape scent as well.
In conclusion, I say give a try with the scents.
Sorry for being so long winded.
Best of luck, Cat9
