I have been shooting montecs for about 5 years or so. I have 0 problems with them. They sharpen easily, Penetrate great, and have killed plenty of deer for me. A few I remember which impressed me. I shot a doe the first year I used them. It went in and out through ribs, hit a rock in the creek then skipped up and hit another a rock. Dulled the point a little bit but that was all. I sharpened it up and used it again. Killed a buck this year with one. Went through both shoulders and into a tree. It's in the case on another arrow to be used again.
