A few years ago I went on a hunting trip to Montana. One of the guys there happened to be the inventor of the Montec. He gave us all free samples. They are probably the most accurate fixed blade broadhead I have ever shot. The only thing that turned me off about them was that they seem to make a whistling noise. All the broadheads you mentioned are worthy of your arrows. Maybe someday, if you've got the cash, buy them all and see which one is the best for you.
