Last year I used Active Scrape and Trails End by Wildlife Research. Trails End in the early season and Active Scrape in the rutting period. I saw half a dozen differnet bucks becuase of it and had a monster 10 point 8 yards from me on the ground checking the mock scrape I had the dripper over. When I went to draw he heard my arrow on the rest and bolted. Later that morning I shot a 4 point over the same mock scrape. I HIGHLY recommend it to anyone. This year we seem to have another 5 or 6 bucks running around our stands from what we see on game cams so it will be interesting. I've never used Code Blue but have heard both good and bad stories about it. Good luck.
