Matt,

First off, welcome to the forum.

To answer your first question, I would suggest the Muzzys. I have no experience with the Grim Reapers but have been relying on Muzzy products for years. Very dependable.

Second, though I have been using conventional camo clothing for years I am starting to turn onto the idea of guillie/leafy suits. In the last year I have bought two leafy suits and have been very impressed with the increased potential for blending into the environment. I have not tried one of the guillie suits personally but have seen (or should I say "not seen") them in the area I hunt. They do look great but I have always been a little concerned with the strips getting in the way of the bowstring.

With this in mind I would suggest you take a look at the new bibs that Rancho Safari has out this year. The basically cover 2/3rds of your body and really make that lower 2/3rds disappear completely. The top part of your body where the bowstring could potentially contact is free of any potential snags and yet it still is not enough to create an outline or give away your position.

If I had to choose a scent eliminating method out of the three you listed then I would just go with the single scent eliminating undergarment as well. It seems the most versatile and reliable in many situations.
