I use carbon shafts exclusively now, regardless of type of bow. I fletch 'em with plastic, because it's cheap, easy, and works. Can they cut you if you hit yourself with em? I suppose....but you can do that with feathers too. And realistically, once you get the knack of shooting, you won't be hitting yourself. Arm-guards, etc to protect you from getting hit are crutches. Use proper form, and you won't need any of 'em
