I was going to post about these on Sat. evening after being out in the yard doing some target practice with both the bow and X-bow. Well I only ended up shooting one of the threeand it hit exactly where I wanted it to and it penetrated about another inch and a half into my McKenzie compared to other tips. Only thing was when I went to pull it out all 3 blades broke of because of how they are curved at the ends (NOT THINKING). But only after one shoot they seem to fly straight and are sweet looking. Only thing is when you go to screw them in and put pressure on the blades they seem to bend. So far the strongest blades that I have found on the market are the NAP blades.IMO....
