Hey 5-Shot,
About 3or4 years ago a friend of mine from arizona gave me a dozen vortex broadheads. I shot several deer with them the first season that I had them. I don't think that they are very durable with the design that I was using. 100 grain 3 blade. I also felt that they were a little bit hard to put together. I can't vouch for the penetration, I was shooting 79# of k.e. so I would have passed through whitetails no matter what kind of broadheads I shot, as long as I had made good shots. "KWB"
