This is the first year that I've used the Silver XP and I really like it. I think it's better than the scent-a-way or scent killer. As far as scent, try the National Scent Company-sex buck scent. It's is by far and away the most effective scent I have ever used. And I have tried all of the major brand and a few of the smaller ones as well. You have to order it, but it is well worth it. A 4oz bottle is about $10, but S&H is like $6 or something.
