what critters are you hunting? hopefully only deer or lesser animals, and not hogs or tougher hide game.
if i hadda hunt deer with a bow that truly held at 43#, i'd want a long, not-so-wide twin blade (many choices) or a tri-blade such as the woodsman, elite, or vpa ... and 11gpp mass arrow weight at the least. NOT SLICK TRICKS!
personally, i would think about holding 50# or more, if possible. light holding weight bows and heavy arrows equate to large trajectories and that limits the effective kill range distance. i wouldn't go beyond 13-15 yards if i hadda hold 43#. ymmv.
