Jeff, I have not shot these...or any other mechanical ever- however, I recently watched a dvd my friend gave me called Broadhead Mythbusting: Science vs Opinion. It was a grim reaper dvd, andshowed grim reapers vs. plenty of other top heads, including rage and snypers, and even fixed heads like Muzzy & Thunderhead. They did all types of tests, and in all of themthe reapers didincredibly well. Honestly I was impressed. They even did awesome shooting through a steel drum, most of the other mechs fell apart. I am not a mechanical guy, as many of you probably know - but if I was, I would give these a try. Their design seems alot better than many of the others on the market, and their strength seemed VERY good, especially compared to others. I can't vouch for them personally, but they are the first mech head I have ever even considered trying.

Edit to say: I do have a friend that shoots these exclusively, the one with the trocar tip which ever one that is. He swears by them, and has a ton of success with them. I have seen some of the holes, pretty awesome. He's the one that gave me the dvd.
