Well I got a Trykon last December and bought a dozen of Axis shafts for them. I never got to shoot anything with it, but those Axis shafts are awesome in my opinion. They are very hard hitting and penetrate a lot better than the old Beman Hunters I used to use. I have never tried the carbon express, but I really like my axis arrows. My Trykon is a 29" draw and set on #72.JMO
