its all about what "fits his bill" as mentioned before. does he want speed for 3d or target shootingwhile during the hunting season he still has a great shooting bow that will make up for a little noise in speed for sure. or does he want a smooth shooting bow with all of the creature comforts so to say. the airbornes would probably be what he weent with if hes thinking pse vs. bt. they are smooth and a little quieter and almost as fast. if he wants a super smooth, dead in the hand bow that is extremely forgiving then the guardian or general will be what he would want. they are slower (the guardian is 10-15fps faster than the general) but they make up for it in the noice and feel department. he just needs to shoot whichever ones he thinks will satisfy him now.
