They had that out last year. I'm sure the X-Force is a great bow. I shot PSE for years and liked them very well. Now I shot Mathews and like them also. I would have a hard time beliving that the x-force is quiter than any of the other bows or has less hand shock. As for Kinetic energy of course it has more its a faster bow. If the other companies bows were as fast as the PSE's then the KE would be the same. To me there comparing apples to oranges. Maybe in a year or two the can do a comparison of shoulder injuries resulting from pulling these same bows back. Shot them all and them pick one out. If your looking for speed they sure are screamers.
