I would go with the CZ, they make very accurate high quality rifles for the most part. Kimber is hit or miss with me, I had a very expensive Kimber 45acp 1911 pistol and it was total garbage for that kind of money. Kimber rifles are nice but also overrated I think for the money the CZ is the best deal.
I do some rimfire silhouette shooting at a club level and around here everyone shoots either CZ or Anschutz rifles. Some days the guys with the Annie's win and some days the CZ's dominates. It always comes down to the guys pulling the triggers, but the CZ's do a pretty good job of keeping up the Annie's that cost three times as much.
When it comes to scent, there are basically two types; those that attract and those that mask. I've tried both on many occasions. There are lots and lots of "doe in heat" scents, designed to attract a big buck into range. I've also used a "cow in heat" scent while elk hunting.
Another scent would almost be better named as a "coverup smell". The main goal is to cover up human odor or mask it. Though I don't believe you can ever totally eliminate all human...
