Just on the light carbon/mechanical thing.

I don' t think it' s a problem . I blew through 5 deer last year with a 350 grain arrow (total weight) and 100 grain Spitfires/100 Rocket Hammerheads. Shooting 300 fps . You may not get that speed at your draw length, but I feel like I have way overkill on mine ! Good Luck !!
