Sounds like your husband has a need for speed. If he is experienced with bows he' ll do fine - but if this is his first I would suggest something on the " lighter" side. Those two bows are indeed fast; however, no arrow will ever shoot past the speed of sound, and he will have to give up a lot of forgiveness and other attributes to achieve that speed he desires. I would flip a coin on the choices - they are both equal in form and function.
