I used to shoot the Rocky Mountain Snypers. I had the opportunity to shoot the Montec G5's. I will start by saying that they shoot just like field points(on a properly tuned bow). The only thing I would say that is a slight negative is that when they are flying, they make a little hissing sound. Nothing big though. They come out of the packs pretty damn sharp and can be easily razor sharp again, using a stone. I was told by a buddy of mine, that a person he knows shot 5 deer with the same head last year and had no problems with them!
