I have used Montecs for a few years now and I have loved them. I have taken 3 hogs and a deer with them. They are really durable, and have a nice size cutting diameter. I shot at a deer last year and missed and it hit a rock, and all it did was put a knick in it, Then all you have to do is sharpen it out. To me these are the best broadheads I've used so far. As far as the Blazers go I have a friend that shoots them, and I shoot quickspins, and his groups are tighter than mine.
