Before having to go the a Xbow (I'm 82) I used Muzzy's and had excellent luck with them. As the Lord blessed me with more birthdays I lightened the draw weight and shortened the draw length until I felt more comfortable with a cut-on-contact head. When I went to the Xbow I tried the Muzzy's but they did not fly consistently. Tried Grim Reaper and Slick Tricks. Both shot well, but ST's were best. Had been considering going to Rage, but am going to stick with the slick tricks. I had nothing but good results with the Muzzy's, and never had to worry about losing a blade. Did often sharpen the new blades. By the way, there are plastic washers out there that ou can put between the BH and arrow to help align the head if necessary.
